Before lobster rolls were trendy in New York, there was Pearl Oyster Bar. Open since 1997, this tiny, no-reservations restaurant still has a solid 45-minute wait for a table on any given weekend night. But those who have eaten here will tell you it’s worth it, whether you dine at the namesake bar or in the cozy adjoining dining room (this is not a place to take big groups). Of course the fresh oysters and lobster roll are sure bets, but don’t overlook whatever whole fish they are serving that day, which can be enjoyed pan roasted or grilled.
