I went here with a friend a few weeks back. It was actually packed by the time we went there, but not to the point where it was too uncomfortable. The place is pretty compact though, like hole in the wall bar small. The stage is also pretty small, so there is usually only one girl dancing.
In terms of the friendliness here, the girls seem to have fun when they can. They'll definitely attempt to get a dance out of you and they're pretty good too.
The bar usually gets swamped, but the service is pretty standard. Nothing to complain about there. The drinks are pretty standard price for a gogo bar at about $6.
Overall, a good place to burn your cash for some good company. I'd recommend coming out here, if you're a small group or solo.
