Fast Food in Seaport District & South Boston

A Southie tradition since 1951, Sullivan's is beloved for hotdogs in the casing, known as 'Sully's snappers.' In 60-plus years of business, the price of those dogs has increased by more than 10 times – making them a whopping $1.90. Fried seafood, burgers and soft-serve ice cream round out the menu. You can't miss Sullivan's at the entrance to Castle Island.
