Last time I was there, Hustlers was around, as was Players. Another place I recommend is Sports Academy and a newer place a friend of mine runs called Breakers. All are in the downtown Asoke area.
Victorl's post is spot on ...although he missed The Sportsman bar.
Basically they are all within 2 blocks of one another ... The Sportsman, Breaker Bar and Sports Academy on or near Soi 13 and Hustler and Player near Soi 12 on the other side.
