I don't know if there are particular specials, but the entrees are meant to be shared family style. Do a single entree could easily feed three or four.
Most dishes can be shared by 2 or 3 people
Back when I was younger I used to have that many at Mary's for my birthday, and they would set up tables special and make special family style dishes. But I arranged that in advance. Sixteen is a lot for a small restaurant, but they handle meal rushes well -- but if you want something good, special for a party, just talk to them. They often have seasonal foods on the menu. For something special, go fresh.
We usually just order one entree pretty person and share everything and that works out well for voracious adults.
