A year of smashburgers, late nights, and questionable choices deserves a proper celebration.
El Burger turns 1 this 4/20, and we’re celebrating the way we know best: burgers off the plancha, music, drinks, and a few extras.

Join us for sounds by DJ Alsueno, shot & cocktail specials by Madre Mezcal, and Sonoma Hills Farm in the mix with Yes Chef & Girl Dinner pre-rolls.

Come hungry, stay loose, and help us celebrate one full year of El Burger in the Mission.

Find us inside the Mission’s favorite lil agave bar, MOSTO.
