Depending on how you look at it, the prices of drinks in Bangkok may be more expensive or cheaper. Alcohol sold in Thailand is subject to tax. However, if you come from places like Singapore, you will find the drinks here more affordable.

Price of beer like Heineken or Kloster for example are about 75B – 110B at most pool bars. The GoGo bars at places such as Nana, Soi Cowboy or Patpong charge 80 – 145B. If you visit some clubs such as Angels Disco you would be forking out 160B a bottle, in CM2 it is 230B. Prices in Spasso (Hyatt Erawan basement) would be generally higher - 210B+++. In Gentlemen's Clubs it is about 300 B.

Okay, where is the cheapest beer bar? Answer: Cheap Charlie's on Soi 11.

A little update on the price of drinks. The recent increase of alcohol tax has increased the drink prices. Most bars have increased it by 5 to 10 baht, however, we noticed that many bars in Nana plaza have decided to go even higher. Beers that used to cost 90 B now, cost 110 B. What a drag!!!

Buying them by the bottles
You could also purchase bottles of liquor. In general most bars charge between 1,500 B for Black Label, some places include the mixers for free, some charge extra. Again, at Spasso, a bottle of Beefeater's Gin is 2600 B++ (6 bottles of tonic included) additional bottles of tonic at 100B++.
