restaurant or hall

here are places in queens:

caffe on the green-bayside
matteo's-howard beach
villa russo's-howard beach
parkside-corona(everyone talks about how amazing the food is)
l'incontro-astoria(one of my favorite restaurants, food is incredible)
ponticello-astoria
ammos-astoria(it is greek food)
mezzo mezzo-astoria(also greek food but will have other things too)
verdis of whitestone
you could even do it at central which is a club but they can do events in the daytime
cavo-astoria(it is a cafe/restaurant and lounge, its huge and has a very big outdoor area which is gorgeous with waterfall and everything. Theres a section as a lounge, a restaurant and a cafe area too)

if you need sites or more info about any of these places, let me know.

eta: i should write where in queens so edited to put in location

I would price out both, sometimes a hall can be cheaper then a restaurant depending of course on where you go.
Good Luck.
