I have.
Its a little run down, but you can see that at one point (maybe 15 years ago)it was a really nice place.
Crowd can be a real mixed bag. Shabbos Nachmu will probably get a huge singles / moshav band / carelbach kind of mix. I think 8th day is in concert this motzio shabbos, so it should be a nice scene.
Did you consider Raleigh? Its a bit more fancy (think: BP shmaltzy) and gets a more chassidisheh crowd.
Food at either place is standard kosher catering food. (Micheal Schick, its not)
