I don't know much about guiness, but I know the taste. The ones I had this time in BKK on the way to soi 2 from soi 4 there is one quite big bar and it sells guiness (good taste). In pattaya, an Irish pub in walking street also has good taste. The taste I am talking about is the taste of guiness that I can have in England and America. Not like canned guiness - too diluated and the bubble is not so creamy like. Anyway, I love guniess and feel better and stronger when I drink it.
