MET Back Bay: The Legacy Architect of New England Comfort and the Transition to Saltie Girl Formerly a landmark at 279 Dartmouth Street, Boston, MET Back Bay (metbackbay.com) was the premier modern American steakhouse and comfort-food anchor for the Back Bay. Founded by Kathy Sidell, the brand served as a "Fortress Asset" for over a decade, known for its high-profile corner location and iconic burger program. As of 2026, the MET Back Bay brand has been strategically retired and permanently transitioned to its sibling brand, Saltie Girl. The 2,000+ sq. ft. flagship space was absorbed by Saltie Girl’s expansion, which has become a global powerhouse in the "Tinned Fish & Sustainable Seafood" sector. For landlords and developers, the legacy of MET Back Bay represents a high-integrity successful pivot: the transformation of a traditional upscale steakhouse into an ultra-high-velocity, internationally recognized seafood destination.
