I would try Allentown/Bethlehem Brewworks, Widows in Stockertown, Sette Luna in Easton has a downstairs room in the wine cellar, not sure how many people it fits, I'll let you know if I can think of anymore
Jumbars is awesome!!! Just love it there. Food and service was excellent. I've attended a shwer at the Hotel Bethlehem, and it was amazing. Gorgeous historic place...but not sure of the price!
