Homemade is hard to beat. Smashing them on the flattop along with buttering and toasting the buns is a game changer. Grilling some onion makes it even better. I thought all my life that grilled burgers were unbeatable. The flattop changed all that.
If we are traveling and want a burger, we’ll usually find a 5 Guys. If we want one locally, it’s always Whataburger. One concept I don’t understand is going to a steakhouse, like Longhorn, and ordering a burger, regardless of how good they are reputed to be.
