Opened in 1951 as a hot dog stand at Castle Island. The current building dates from 1986.

Why it matters

Dan Sullivan Sr. opened a hot dog stand at Castle Island in 1951. The family added a second structure in 1963 and built the current one, modeled on a fort officer's residence, in 1986. Four generations of Sullivans have run it.

Its opening day each February or March is treated as the unofficial start of spring in South Boston. In 2025 it won a James Beard America's Classics award for the Northeast.
