Crone’s father began the J.A. Sanborn Company forty-nine years ago at 28 Merchants Row (next door to Quincy Market), and it’s still flourishing. “We go out of our way to buy the best,” Crones told us. “We buy whole fish off the boats, and cut them here. You can always find a good selection.” If you dine at the Ritz, or at St. Botolph Street, you’re eating Sanborn selections, and Crones will even mail fresh lobsters for you.
