Our Home—Where It All Started

Located just steps away from the iconic Fort Independence, Castle Island is the quintessential New England seafood shack. This location has been in the family for four generations now and is our flagship store featuring our whole menu of quality food at affordable prices. If you’re looking for the most authentic Southie seafood experience, this is the place to be.

Welcome Back!

Since closing our Castle Island location at the end of March, we have been hard at work implementing new systems and guidelines that would enable us to safely serve our customers when the time was right to reopen. In addition to new Safety Guidelines, we have created new Online Ordering (, new phone ordering, and a process to take walk-in orders on a limited basis. Our goal is to deliver the same great Sullivan's food and value loved by generations of Bostonians with our same great speed, efficiency, and good humor. We hope your visit to Sullivan's Castle Island gives you and your family some relief and enjoyment during these unprecedented times. Thank you for your support. Please continue to be safe.
