I have to agree with you Kahuna. Promotion is key however location is also important.
The thing about KOYO was I always felt I was in the middle of Las Vegas picking out a hooker for all and sundry to see. While on the other hand, EZY, Famous, Sunnee, Soi 6, was/is somewhat more discreet (perhaps in my own head) and as a result I was more comfortable.
Koyo was just too loud, too bright, too present, too in your face at the entrance to the loudest place in Pattaya.
