When I lived in Bangkok I seldom went to the British / Irish Bars except when there was a sporting event on I wanted to watch with a good atmosphere. I think the reason being that a British or Irish name and some decor, and a token pint of Guinness does not make a pub or bar that feels British or Irish. They feel as British or Irish as Hard Rock Cafe in Pattaya feels American. So on that basis I would, and still would, prefer to meet people or go for a drink in a local owned place because they are usually not a disappointment, where as the British or Irish places generally are. Therefore I would assume they exist off of tourists Baht and not immigrants to Bangkok's Baht, so the places remain where the tourists go. Not sure why places like Taffy's Hairy Pie Club closed though and didn't relocate to the burbs - that famous Welsh venue. Would have done very well in Bang Na near the convention centre 🤣
