Need a place to host a reception the size of 250 anywhere in 5 boroughs

Looking for something affordable (5-7K) and be able to bring in an outside caterer for kosher reasons, Thanks for your recommendations in advance.

If you asked on the Outer Boroughs board, I would suggest the Prospect Park Picnic House (but 175 person sit-down; 250 cocktail style).
