Searching for a quick fix of prosecco and bivalves? There may be no better option than Barbara Lynch’s subterranean South End eatery, which carries a daily selection of more than a dozen different east and west coast oysters. The cooked classics are all here, including fried Ipswich clams and a pair of lauded lobster sandwiches: a classic lobster roll and a lobster BLT. Seasonal fish dishes might include mussels fra diavolo or Faroe Islands salmon with ratatouille. When the weather allows, the backyard patio is a popular spot for alfresco slurping.
