Our Grand Opening!

Hi,
A group of ~ 40 teachers/administrators/staff from PS5 are looking for a place to have supper on Thursday June 14 to celebrate our teacher of the year. We would be getting there around 3:30/4:00 and leaving around 5:30/6:00 before the rush period.
Doesn’t have to necessarily be a separate room (though if you have that let us know) but we’re looking for a partitioned space, apart from the regular crowd, so we can talk, etc. Let us know if you have such an area available. Also, how much per person?
Thanks!
