In Lower Pacific Heights? Your internal burrito GPS will point you toward El Burrito Express 2 (the original location is in Parkside). The casual counter-service spot consistently hits all the marks that make for an excellent super burrito, with tender meat (there are a ton of seafood and vegetarian options, too), and a balanced mix of crema, guacamole, and pico de gallo. In the non-burrito department, they have soft and hard-shell tacos, loaded fries, and serve breakfast all day.
