WHY WE LOVE IT: Is it a burger or is it a Frisbee? Thankfully, the 6-inch discs coming of Grandpa’s griddle are burgers, flash-cooked and served hot on buns with plenty of ketchup and onion. Get it to go, then eat it on the hood of your car in the parking lot. WHAT TO GET: #1 combo: Double burger, fries, shake.
