A gorgeous back patio secret in Hayes Valley

One of the most overlooked/underrated patios in all of SF, this Hayes Valley eat spot's back end is shaded by trees and infinity lush, green plants, and boasts a flagstone seating area from which you can take down the "Staff Meal" -- three crispy skin duck confit tacos on corn tortillas in a spicy mole sauce with a hunk of queso fresco, red onion cilantro and toasted sesame, also the password to get into little-known X-Factor superhero Bong Guy's secret lair, which is actually just a studio with wall-to-wall shag carpeting, a String Cheese Incident poster and, like, six bean bag chairs.
