I know, I know, who spends time in pubs in the city of Bangkok?
Well, I did
But I was there for 3 weeks and wanted a refuge.
The Black Swan was a great English pub!
Simply fantastic food, best bangers and mash, fish and chips, etc...
Most of the British imports on tap, in 20oz pints.
Even had Tiger Lager, which while very light is great when hot outside.
If in your in Bangkok, try the Black Swan.
(It's even in walking distance from Nana Plaza and Soi Cowboy, but I, of course, never set foot on either street.)
