England vacation!

Where in Pembrokeshire will you be? I lived in Solva (near St. David's and Fishguard) as a kid. Sloop Inn is a great seaside pub in the area.

 

I'd recommend trips to Manorbier (beautiful little village with a castle overlooking the sea) and Saundersfoot (nice beach, a few good pubs and a little shop near the beach that sells local beers as well as other alcohol). Pembroke Castle is also lovely. Not a huge amount going on beer wise, best to follow the Camra pub advice.

 

Bit out of the way, but I really recommed Mwnt beach. Also big fan of Stackpole, Tenby and St David's. After St David's you should go to the Lifeboat station where you can walk a small part of the Pembrokeshire Coast Path.

Beerwise, I can recommend Tenby Brewing Co. The Mooring in Tenby is a really good restaurant.

 

In Manchester city centre I would recommend the following places:
Piccadilly tap
Port street beer house
Cafe beermoth (they also have a bottle shop not far from it)
Brewdog
57 Thomas street
The Smithfield tavern
The knott

For more traditional pubs try
The castle hotel
The Marble Arch
The Angel
Sinclairs

 

Keswick (pronounced Kesick), The Dog and Gun (CA12 5BT).
London, I always recommend the Harp.

 

In York you have a plethora of pubs that suit all tastes from trad ale to craft beer.
The Blue Bell, old tiny trad ale pub.
The Starre Inn, old larger trad ale pub
The York Tap. Part of the York train station with a good mix of craft and ale.
The Three Legged Mare
The Rook and Gaskell
The Guy Fawkes Hotel, local boy celebrated as the only person to enter Parliament with honest intentions. Lovely oak panelled gas lit pub next to the Minster.
House of Trembling Madness on Stonegate. Awesome bottle shop downstairs.

 

+1 on the Dog and Gun, we also liked the George hotel.
No guns , but lots of dogs
If you get to Lake Buttermere the Fish Inn was a cosy pub
with a nice variety of real ales.

 

I'm NOT trying to sell the place to you but I called it the GF Hotel when it's the GF Inn so I thought I'd best set that right...

And Hawkshead Brewery and beer hall isn't a million miles from Keswick and is worth a trip
Coniston Brewery's Black Bull pub is within easy reach too. Brewers of some of GBBFs Champion ales.

Betty's tea rooms in York are worth a punt if tea, sandwiches and copious amounts of cake in genteel surroundings are your bag. Yorkshire Curd Tart, a warning! don't ask for Turd Cart like I did.

 

London:
Beer mile in Bermondsey (Saturday only)
Any of the Craft Beer Co. venues (great booze)
Princess Louise in Holborn (beautiful interior)
The Rake near Borough Market (great booze)
Ye Olde Cheshire Cheese on Fleet Street (olde)
The Harp (pint of Harvey's Best Bitter)

Enjoy.

 

Two classic historic London pubs.

A really good guide to London is "London's Best Beer Bars and Pubs" by Des de Moor. It won't be 100% up-to-date but it covers both "traditional" i.e. real-ale and "craft", and is a good place to start.

The Good Beer Guide 2016 (2017 is released in mid-September) covers the whole of the UK, but "only" covers real-ale. It also has a complete list of real-ale breweries on the UK.

Useful websites include:

Whatpub (covers the whole of the UK)
Craftbeerlondon
Beerintheevening

My advice would be to try a mix of "traditional" (there are some really fabulous beers from longer-established regional and micro-breweries which perhaps don't get the respect they deserve in some quarters because of the recent explosion of new breweries) and newer "craft" beer.
