Many people either don't know about 9 Lounge or are confused about it, so I thought I'd put in my 2 cents to put it on the Yelp map.
This is primarily a dance club. I think it's open only on weekends. I really haven't spent more than a few seconds inside because dance clubs aren't my thing. (anyone who's seen me dance, trust me, is thankful for that). But it does get fairly packed.
It's run by the coolest sports bar in town, Majerles, to which it is directly connected by a single door near the back. So, if I'm not mistaken, there are actually 6 different bars/lounges right on this corner of Washington and 2nd Street downtown.
EDIT: From the photo I'm looking at above, it doesn't exactly look like a dance club. Maybe I was too inebriated whenever I visited this place to understand what the hell was going on. If anyone else stops by feel free to correct me.
