Went with 3 friends on Labor Day weekend (Sunday night). We all live in different towns, and Dedham is central, so it's great that Summer Shack takes reservations. The weekend bartender is so friendly and funny. When we had a friend running late, the hostess was really accommodating to us being seated 30 minutes later than our original reservation. Our server was fine. Seemed a little uneducated about the menu (didn't know if the Sea Bass was Chilean, Mediterranean or something else). Not a big deal though. Whatever it was, the sea bass was terrific!
