Two words: FREE WINE.
Every Thursday, they offer free wine from 6 - 8 pm. Just RSVP, and you're instantly granted as much free wine as you can drink for two hours. They usually have a selection of two whites & two reds - which change a bit from week to week. All you have to do is tip a dollar or so. Well, I guess it's not really required to tip - but don't be an asshole.
As far as the night club goes, it's pretty decent. They have open bar for ladies from 10 to 11 I believe? Maybe even until 12. And they make their drinks pretty strong, which for me, is always a plus.
In comparison to other night clubs - it's nothing special. I go to Lavo, simply for the open bar. If it weren't for that, I probably wouldn't go there oo often.
