Soul food and Boston isn't a connection most people make, but they might after a visit to Bob's. This lively spot is a hit, with authentic southern classics such as black-eyed peas and collard greens as well as the New Orleans-tinged crab cakes and jambalaya. The Sunday jazz brunch (10 am-2:30 pm) brings together a fun and diverse local crowd. Jazz also is presented Thursday-Saturday evenings and some Wednesday nights. The restaurant is popular and safe, but be cautious in the surrounding neighborhood at night. Monday-Thursday for dinner only, Friday and Saturday for lunch and dinner, Sunday for brunch and dinner. Reservations accepted for parties of four or more. $-$$. Most major credit cards. 604 Columbus Ave. (Massachusetts Avenue T stop on the Orange Line), South End, Boston.
