There is a group of us that go out to dinner once a month and we typically stay around the Back Bay/South End where most of us live. I fee like we've hit most of the restaurants there so I want to look to Cambridge next. Can someone offer up some suggestions on some places in Cambridge (Central, Davis, Inman, Harvard, etc) that a group of 10-12 would work. Looking for nice places, but more importantly excellent food ($18-25 range per entree). I've heard of some places (Rendevouz, Central Kitchen, Salts, etc), but don't know many people who have actually been there. Any help is greatly appreciated.
