dinner for a large group

[bookworm]

I'm looking for restaurants that can handle a ~20 person dinner party, that meet the following criteria:

--inside/around Rt 95/128 (but not in Boston!)
--cost around $25/person
--any cuisine
--slow paced meal so that any late arrivals won't be too left out

Please help! The resuarant I was planning on using just told me they didn't like to accommodate large parties on a Friday night, and I'm feeling pressed to find another option.

It may be a bit far for you, but what about Lyceum in Salem? Great food and several areas that could accomadate a party of twenty. We ate there the other night and it was still excellent. We've also been to a wedding there and the food was equally good.
