I have had some Guinness in the Metro Sports Bar in LK Metro, 220 baht a pint, tbh the same as in the U.K., fully air conditioned and over 12. TVs, no girls pestering you. Around 30 farangs in the bar, the Thai lady knew exactly how to pour it albeit I think she was was frustrated she had to do 75% let it settle then 25% to top it up.
i spoke with owner, very popular seller he sad, it was imported from Dublin unfortunately when the current stock runs it out it takes a month for the next delivery. I am not sure why they didn’t re order before they ran out ?
