Castle Island's seasonal staple has about a month left before it shutters for the winter. Sullivan's, a fourth generation-run restaurant in Southie, will offer half-priced hot dogs starting November 1 until its closing day on November 29.
Sullivan's has been an institution in South Boston since 1951. The restaurant closes ahead of the winter in Boston and reopens the last weekend of February each year. It is known for its hot dogs, fried seafood, and lines out the door.
