I am looking to throw a 21st birthday party in Center City for up to 150 people. I would like a late night party with a DJ, drinks, hors d'oeuvres, and a cake. Does anyone have any good suggestions on where this could take place? Maybe a funky restaraunt, lounge, or a club?? Must have space for dancing...It will be in Februaury. Thanks in advance for your help!
