A bit off the beaten path. There are lots of Brazilian restaurants and stores around, including a Brazilian butcher-slash-convenience store. The Brazilian community extends to Inman Square and there's another pocket in Allston.
The Neighborhood Restaurant and Bakery is worth visiting the Square for, especially in the summer months. There's an overhead grape arbor with real fruit growing on it. There's a large breakfast/brunch menu, and very colorful outdoor decor. The menu also includes some Brazilian fare.
