Gone are the bland burgers topped with nothing but lettuce, onions, and pickles. The classic sandwich and its potato partner-in-crime get a crave-worthy revamp at California-based BurgerIM. The quick-growing franchise, which was founded in 2011, boasts a menu of chef-inspired, gourmet burgers in 3-ounce portions—perfect for mixing and matching—or larger, single-serving sizes like quarter- or third-pounders. With 11 varieties of patties, patrons of all eating habits can find a match made in burger heaven. Aside from standout sandwiches like crispy chicken, Hawaiian salmon, and Greek lamb, BurgerIM serves salads and meaty wings, plus milkshakes and sides like onion rings and fries.
