Best soi for a quiet drink is soi eric, kiran bar, good girls.
Pity about the music though, the dj is a pissa, a mate was telling me he snuck up behind him once and he was just browsing other things on the laptop, and then we the dj saw him he quickly went back into his "dj program" and started fiddling with the controls. 555
Also at about 10:00pm, there is always the same song with the recording "welcome to soi eric, welcome to soi eric"..555
But if your up for partying, definately tiger bar complex.
