If you’re in the Outer Richmond, and in need of a perfectly-square katsu sandwich right now, head to Bread N’ Chu. The sandwich shop makes a really good one with a thick, crispy chicken breast, shredded cabbage, a generous layer of Kewpie mayo, and crustless milk bread. They make other sandwiches, too, like tonkatsu and choux sandwiches, but the katsu one is the star.
