Why not list those hostelries in your area worth a look as a helping hand to those who find themselves away from home and in need of sustenance?

I'll keep the OP up-to-date on a city/town A-Z if it takes off.

Belfast

The Crown listed building, gas lighting, snugs with bell presses etc. Bit of a tourist trap but worth a look. Some local ales.
The Garrick loads of bottled beers, guest beers etc. Some trad music toward the end of the week. Comfy. Gets a big work crowd during weekdays. Big on sports coverage. Decent grub.
Duke of York impressive whisky selection - can get mad busy at the weekend.
John Hewitt Guest ales, good selection. Big live music venue (quite eclectic) - round the corner from the Duke and can get pretty busy.
White's Tavern Olde Worlde - been around for a long time (centuries). Mixed crowd - can be a bit touristy. Some music too. Can keep odd hours during the week and may close early. Shares a courtyard with The Monaco which is another decent older pub - but stay in the front bar of the Monaco - the back lounge gets a funny crowd for some reason.
Love & Death Nice chilled-out cocktail lounge.
The Spaniard Small, chilled out, big on cocktails but has the usual tap beers too. Great spot
The Merchant Hotel Cocktail Bar Incredible bar - was voted best in world a while back - expensive but worth a view if you have the money. Have to be seated to get served.
am pm Restaurant - bohemian decor and nice grub at a decent price. Chilled out atmosphere. Close to the Garrick.
Nicks Warehouse Restaurant  - institution - great grub and a wee bit more expensive but worth it. Excellent atmosphere - close to Duke of York.

Berlin

Katerholzig One of the best. Half indoors, half outdoors. Run by the old (and infamous) Bar25 people, you'll mostly find tech-house, deep house and electro swing. It's best when the weather's good, as most of the parties then take place outside. The inside is decorated a bit like some kind of surreal circus, and the regulars are equally strange. Beer is 3 euros, cameras are forbidden, drugs are openly consumed just about everywhere, and there are no mirrors in the toilets. To give your self the best chance of getting in, dress the total opposite of how you would if you wanted to get into a British club. The selectors have a soft spot for weirdly dressed people who look like they've had no sleep for 3 days.   edit- ive never seens kids there before, so not sure why they're in this picture.  

Sisyphos Set in an abandoned mansion, Sisyphos is the Berliner's party destination of choice due to its lack of tourists. It's 50% indoors and 50% outdoors so best in summer, but it's not close to any transport links, and you'll have to get a taxi or shuttle bus to get there. It's famous for it's lengthy opening times. Last weekend, for example, the party started at 10pm on Sunday, and finished at 8am on Tuesday. You can stay there for start to finish, should you have the stamina. If not, there are sofas and mattresses where visitors can get a few hours sleep (if they can ignore the thumping techno). Drinks operate on a 'pfand' basis. So although you can buy a beer for 3 euros, you can alternatively pick up 6 pieces of litter and get a drink of your choice for free. Stalls line the exits to the clubs numerous dance floors. They sell homemade pizza, fresh soup, sweets and chocolate. For a surreal experience, try clubbing here at 11am on a Monday morning.  

Beverley

Nellies (technically the White Horse Inn, not that anyone calls it that.) It's several hundred years old, and looks it. There is random crap filling the place, like an ancient range cooker, benches and work surfaces and bookcases. Take a tour. You can buy a round for about the same price as a pint would cost in London. In fact Google has led me to this Independent article about it: In the pub where time stands still: A Yorkshire town and its ramshackle inn have survived the era of 'progress' towards blandness, as David Hewson discovered Nellies, and Beverley to be honest, haven't changed much since that was written in 1994. They built a Tesco. That's about it.

Cheltenham

The Montpellier Cracking little place. All the food is ace, as are the cocktails. Sunday lunch however, is it's crowning glory. The Strand Also does a good roast, the food is generally good and it's certainly good value. It's all done by one guy in a tiny kitchen and the pub itself is great; always good ales available. It has a nicely decked outside area and is adjacent to the small but lovely Sandford Park when you need to walk off the roast.

Le Champignon Sauvage Can't mention Cheltenham without this 2 star heaven. I've only been twice in all the time I've lived here as it ain't cheap. The decor is bizarre for the sort of place it is and the service is great but on the wrong side of stuffy for my liking. However, the food is insane; I haven't eaten in many fine dining restaurants but it's been the best food I've ever tasted. The huge wine list doesn't bend you over either; last time we had their cheapest Marlborough Sauv Blanc (about £25 if I recall correctly) and it was absolutely delicious. There's silly options too if you're silly.

The Railway A bit out of town but if you're keen on ale and sausage, it's the place to be. The menu is based around a huge selection of excellent sausages; you're basically going for sausage and mash... amazing sausage and mash. They also have great outside seating.

The Swan Opposite The Strand. A quirky place; it's had a troubled past with many management changes but still remains a great chillout place. Plenty of sofas and low tables and (finally) some really good food.  I've only just noticed that their website is somewhat similar to The Railway's. If that means that The Swan is now under The Railway's wing, it explains the improvement in the food.  

The Curry Corner So the best is saved for last. They came second in the Indian section of the Gordon Ramsay show that pitted various cuisines against similar, losing out to an obnoxious set of chefs from Leeds. (I'm sure their food is amazing) It's a classic family operation, open since '77. Grandad's the head chef and I've never been there without him running the show. As soon as he sees us he whips up a quick tarka daal and personally brings it out to my daughter and makes a huge fuss over her. It's that kind of place. He's always doing the rounds when not on the pass; the consummate host. It's not your average curry house and the prices reflect that. Then you put fork to mouth and suddenly realise that you're ripping them off... Edit:

Purslane How could I forget? Fantastic place; really small and a stone's throw from town centre. 5 starters, 5 mains and 5 puds round out a simple a la carte menu of exquisitely cooked food. There's a lunch menu, too. Cheltenham is riddled with many other great eateries and boozers but my fingers are now tired.

Edinburgh

fine dining Behind London, Edinburgh has the second largest concentration of Michelin starred restaurants in the UK. Best news is, they're mostly well cheaper too. Here's the ones I've been to
The Kitchin You'll know this one- Tom Kitchin is becoming ubiquitous on cookery programmes. The good news is his food is fuxking ace. Very very Scottish food, and his restaurant has a motto "from nature to plate" which despite being a load of wank sums up the place pretty well. You can get in and do an incredible 3 course (well, plus bread, amuse bouche and petit fours) for £25 and stick another £25 on top of that for three generous wine matched glasses. Have been three times and am booked in for a fourth in June.

21212 The basic concept behind it is that you get two options for appetisers, one for fish, two for main, one for sorbet / palate cleanser and two for dessert. It's a bit more "wacky" than The Kitchin but also delightful in its own way. Just be prepared for a lot of foams.

Gardener's Cottage About 100 yards away from 21212, not Michelin starred, but still very very good. Complete set 6 course meal, changes every day (follow their twitter!) and £25 for it. Again, another £25 for SIX glasses of wine and I swear the measures are huge. The restaurant is tiny, they're playing music on a vinyl player and you're right next to the chefs plating up. My new favourite place to dine.

For the Scruffs Pierre Victoire Remember these? Dirt cheap French food? Well after he went bust, he went back to one restaurant which handily is round the corner from me. He's always in rubbing his belly and laughing, and the food is just a pile of awesome food. Set menus for £7.90(!) at lunch and £10 at dinner.

Chop Chop Winners of that Gordon Ramsey search to find the est restaurant in the Uk. This place specialises in dim sum- specifically dumplings. All the dumplings you can shove in your mouth to be honest. Once you've paid for a batch of 8, the next 8 are free YAS. Dirty Chinese food

illegal jacks/Los cardos You wanna burrito? Go to one of these two. Both have their specialities. Jacks has te best carnitas in the world and ledge on draught. Cardos has better guacamole and a haggis burrito. You'll pay about £7 and not need to eat for the rest of the day. sabor criollo Down in stockbridge, a Latin American restaurant where you order something and it jus comes as a BIG PLATE O FOOD, no fajitas or any of that guff here. Set dinner for £15 is well recommended

Kismot These chaps have been on the tellie for selling the hottest curry in the world (you have to sign a disclaimer before eating) but the rest of their food is fun and innovative, a bit different to a standard Indian. Which brings me to... Tanjore Took Shabby Et al to this. BYOB, no corkage, and cheap food. It's southern Indian, meaning its not your standard curries. Lots of lentils and such. Hard to spend more than £20 here. As it is in...

A Taste of Africa This tiny place in Leith does the best jerk chicken I have ever had. The guy just comes out and tells you what's cooking. Again, BYOB and no corkage. The goat soup is amazing.

pubs/bars [
b]Treacle[/b] A Regstock institution. A cool bar, good burgers, potent cocktails. A little pricey for Edinburgh, but a place to also be "seen" (Seen staggering out amirite)

Bramble I spent £30 on four cocktails in here last Thursday an did not regret it. Since the demise of the raconteur, it is the best cocktail bar in Edinburgh. You have to KNOW where it is as there's no sign. Usually djs inside, sexy ladies, and hard alcohol cocktails.

the hanging bat Without doubt my favourite place in Edinburgh. 16-20 beers / ales (although they'll tell you an ale IS a beer...) on at any onetime. The staff know their shit, everything is sold in 2/3 pints, it's cheap, and you get some of the best pulled pork / hot dogs in the world. And Britpop on the stereo. FUCKIN LOVE IT.

the cask and barrel An old mans pub with about 8 different ales on. Pretty standard, but fitted with 12 TVs so ace for the football. Dirt cheap too. Kaz knows what I'm talkin bout

the red squirrel At the other end of lothian road from the hanging bat, a nice pub with good food and a huge selection of beers. I do love it, but sing the bat swooped in, the squirrel has been in distant second

Glasgow

The Laurieston Bar. It looks vaguely terrifying from the outside, and forgetting for a minute the old manager was stabbed to death, is actually a terrific boozer. Edit: There's also a "secret" smoking room.

milton kenes The Barge Every single place in milton keynes is shit except for here. Cosy pub atmosphere, good drinks, seasonal menu and all well cooked food.

Radcliffe
The Royal Oak - A classy affair. If you like your beer cheap, your women exceptionally rough, and a venue's atmosphere to be suicidal/depressing then this is the place for you. Drink until your eyes bleed! Get drunk on a tenner! Smash a glass into another patron's face! Roll up roll up one and all!

BBQ Land - Located in a prime location, near the library and not far from the bustling town centre, BBQ Land is the go to restaurant experience in Radcliffe. Whether you like meat, or more meat, or possibly more meat, this is the king of all dining experiences. Several types of pizza, five different types of kebab, chicken out your arsehole. Whatever you want (as long as it contains meat, lacks salad, and tastes vaguely of nothing) under one roof! While you wait, why not get drunk in the pub next door, then after picking up your order (BBQ Land has no seating inside. "Its a revelation! Just like eating on the streets of Mumbai!" - Danny Boyle) wander over to the library, spill hot sauce everywhere, piss in the kid's section and pass out after failing to touch up the aged staff. Highly recommended.


Wiltshire

The Red Lion Free House - East Chisenbury A very nice little restaurant that pretends its a pub. They have a pretty decent chef and a seasonal menu. Its a great place to go for lunch in the summer due the having a nice little garden out the back. That's where they keep their pigs and chickens. You can feed the pigs apples that have fallen from the trees if that floats your boat.

The Shears - Colingborne Ducis A nice little pub that pretends its a restaurant.  Again really nice food from a good chef, but probably a notch lower on the gastronomy scale that the Red Lion but it has a cosier atmosphere and there are always a couple of locals propping up the bar. Again good in the summer as it has a nice little courtyard to eat in. No pigs but the owners sheep dog is usually knocking about. A very shy dog whilst also being incredibly inquisitive.

Anooka - Salisbury A wonderful Indian place that does very good, modern Indian food. They have a magician in on Thursdays for some reason.
