Friends are looking for a restaurant in Center City to have a pre-bar hopping 21st birthday dinner for their daughter. They want to have 20 to 30 people in a restaurant that can accomodate a private party. They don't want anything too "ethnic" - i.e. no Indian, sushi, etc. And they are looking to spend about $30/head including maybe limited wine and/or beer. The time frame is mid-March. Any suggestions would be much appreciated.
