“Another round, please.” = kor peum eek.
Between the hustle and bustle of Bangkok and party-hard beaches, drinking is a major way of life throughout Thailand. There are very few regulations regarding alcohol consumption, making it a worry-free experience for travelers. Fortunately, alcohol is consumable in public (avoid drinking in and around temples) and identification is rarely checked. With that being said, police will randomly raid establishments looking for underage tourists. If you are not 21, I strongly advise against taking the risk.
