I declare today a victory in toroidal foods. I was in Medford for my follow-up with the ENT (which went well), so I stopped by Donuts with a Difference afterward, and then I returned home circuituously by way of Bow Market in Union Square, where I got a hot bagel with salmon belly lox and caper-parsley cream cheese from Hooked. The counterman was one of the owners, a former chef and current fisherman; he told me they're still waiting for the season to really start, but in the meantime their fresh oysters, salmon, scallops, and skate wings looked lovely. They sell smoked and fresh seafood, bowls, tacos, soups, bagels. There is a giant squid with a tangling armful of buoys and irons painted across their wall and much of their floor. And they are about twenty minutes' walk from me.
