My birthday is in a few weeks, and I'm looking for a nice but not too expensive place for a group to go. There will probably be around 8 of us, but could be up to 10. Would prefer somewhere with entrees in the teens up to low 20s. I would love to do East Coast Grill, but I think my friends are too lazy to get there, especially in this weather. Any part of the city that is T accessible is fine, although downtown, back bay, north or south end are best. Also, we have one vegetarian so need some non-meat/fish options. Thanks!
