Helpful hint: if you eat there on a Friday or Saturday night, make sure you stay for the club/lounge part and you won't have to pay the $40 to get in. I've been there twice and the food is good, nothing I'd rave about. But the place is very trendy and the ambiance and service is up to par.
They sometime have celebrities and high profile guest djs. The first I had been Benny Benassi was the dj. The mor recent second time I've been back, I just went to eat (it was during the week)then headed over to XS.
