Smashburger in Boston's Back Bay Has Closed

Another location of a Colorado-based chain of quick-casual burger restaurants has shut down.

According to a poster within the Friends of Boston's Hidden Restaurants Facebook group page, Smashburger in Boston's Back Bay is no longer in business, with a check on the website for the chain seeming to confirm this, as the Boylston Street outlet is no longer listed. This comes on the heels of a location of the chain in Medford shutting down toward the end of 2025, leaving the local area with locations in Attleboro, Natick, and Westwood. (Another location in Plainville is gone as well).

The address for the now-closed location of Smashburger in the Back Bay was 545 Boylston Street, Boston, MA, 02116. The website for the chain is at https://smashburger.com/
