"In San Diego, most residents know that “smash burger” is synonymous with the Friendly. With four outposts spread out across the county (Convoy, North Park, University Heights, and Pacific Beach), this no-frills dining destination is the perfect place for a quick and affordable smash burger. The Dirty Flat Top cheeseburger, the restaurant’s classic fix, features two patties with crispy edges, butter-braised grilled onions, American cheese, and garlic aioli for $8. The laidback burger destination also offers different burger selections like the $10 Lambo Boiga with lamb and beef smashed patties, Grand Cru Alpine cheese, pickled red onions, pink peppercorn aioli and Madeira sauce on the side for dipping. Hot tip: Look out for riff-y specials on fast-food favorites like the “McRib Kinda,” with deboned ribs, smoked sweet onions, and pickles for $10." - Roxana Becerril
