Butter aficionados rejoice: these aren’t your average burgers. This Glendale spot is has achieved national acclaim for it’s legendary “butter burger” – the addition of a thick, creamy slab of Wisconsin butter onto any of their juicy, sirloin patties. Solly’s has been serving up these caloric concoctions since 1936, but it’s adapted to contemporary interests; for the faint of heart (literally), the kitchen is willing to let you substitute olive oil or a gluten-free bun. It’s your call, but let’s be honest: the thick malt milkshakes are going to get you in the end anyways.
