Sullivans Castle IslandGrab a snack at Sullivan's during your visit to Castle Island. Hots Dogs, Seafood, Lobster Rolls, as well as a terrific breakfast menu. Don't let the long lines deter you - they move food fast!

Back in June of 1951, Dan Sullivan, Sr. opened the stand for the first time offering quality food at reasonable prices and for four generations Sullivan's philosophy has remained the same.

Whether you make Sullivan's part of your daily constitutional around the Island or are visiting us for the first time-welcome and thanks for being part of the tradition!

  • Our customer appreciation weeks are legendary.

  • Back in the day, when Dan Sr. was running things he would quietly hand out ‘cocktails’ (a.k.a. hard liquor) to customers during the last week in November as a way of celebrating the season and saying thank you. Dan Jr. put the kibosh on that in the 70’s. As a replacement, he offered half price hot dogs during the closing weeks. We happily carry on the tradition-on opening weekend and the entire month of November we offer half price hot dogs.
