Southern Thailand is predominantly Muslim which means that portion of the population seriously does not condone alcohol consumption. Alcohol is available in some restaurants and in most mini-marts. There are a few bars downtown and some other places with karakoe machines in the surrounding area. Generally it's not a hot spot for three day drunken clubbing binges but the dedicated Bukowski fan can still get some work done.
For cool drinks and food ... "Port Satun" at fresh market and Rientong peer.. for FREE information tourist , trips , rent .. etc.
