I suggest the one I´ve heard is the best, or one of the best in NYC: Cream, 246 Columbus Ave at 71st Street. (212) 712-1666 Two dance floors and four theme rooms let you lounge or dance the night away. $20 cover. Hours: Fri. & Sat., 10pm - 4am. Subway: B, C, 1, 2, 3, 9 to 72nd St.
you may consider going to some nightclub where famous, good djs play, and there is a nice sound system...sure there´s plenty of them in NYC... and you´ll find ISTPs on xtc by seeing that they´re drinking MINERAL WATER in the club. Go! if you have heart problems or high blood pressure, don´t take xtc. gogogogogo
