Hands down, the best burger in Pittsburgh. Many others have commented on the great milkshakes, the toppings, the bun, etc., but for me it comes down to the hamburger meat. It is high-quality, freshly ground, and hand-formed into patties, giving their burgers incredible flavor, in a form that just melts in your mouth. Nothing else can compare. I'd probably come here every day if it wasn't for the 3,000 or so calories I consume on every visit. And I split my burger and shake with my wife!
