Need recommendations - NYC
Do you have any budget constraints or location preference?
Off-hand this will be my pick:
Devi for upscale/yet not stuffy.
Bukhara Grill for middle range
Bricklane Curry House for reasonably priced and edible ;-)
You may have to close the whole Bricklane for a party of 50 though as it is not a very big space.
