What is the best bar in Baltimore to host a decent size going away party?

The ideal establishment would have the following attributes:
Booze of all varieties, decent food (not white table cloth, but also not Chuckie Cheese), flexible policy on bringing in outside food (sheet cake/desserts), Karaoke (specifically on Fridays), the ability to serve beer in pitchers, Happy Hour specials, and adequate parking (long shot, I know).

Any hints on good places near downtown Baltimore would be fantastic, and very much appreciated.
