By Degrees, at the beginning-to-gentrify corner of Central and Eastern avenues, is not quite in Harbor East, not quite in Little Italy, not quite in Upper Fells. It contributes to the growing number of restaurants—anchored by Heavy Seas Alehouse—in an area also populated with hip co-working office spaces and gorgeous rehabs that house young professional types. The interior is spare, with about 50 seats and a small bar, with decor that features brick walls, one painted white, exposed ductwork, concrete floors, and bare wood tables and chairs. The only soft elements in the place are the black cloth napkins and the light fixtures, suspended glass urns that, combined with the loft-scaled window looking west to Central Avenue, create a mellow glow in the evening. Even so, the place is several degrees from atmospheric.
