Where to Eat the Best Burgers in Seattle | Eater Seattle

"Fireside Burien bills itself as “serving Midwest comfort food and hand-crafted cocktails with a vintage vibe.” Giving some geographic forgiveness, the burger of choice here is the Oklahoma onion burger. It’s smashed but still juicy, topped with American cheese and lots of caramelized onions. The only other ingredient might be the most important one: Yellow mustard whose tanginess rounds out the ensemble. Know before you go: When you order, ask them to not skimp on the mustard, as reports are they’ve backed off the amount they originally provided." - Jay Friedman
