Operating out of an Airstream trailer dotted with surf-shack signage, Güero has narrowed its output almost exclusively to tortas—roughly speaking, the submarine sandwiches of Mexican cuisine. These are fat two-handers piling mounds of avocado, cabbage and pickled onions atop Veracruz Bay Bakery bread. The meat selection rotates and doesn't lend itself to memory quite as much as those copious veggies—which gain additional kick from the cart's signature sauce, a carrot-habanero salsa available by the squeeze or the jar.
