What do you get if you combine a classic cheeseburger with a grilled cheese sandwich? If you’re Sonic, you get the Grilled Cheese Burger.
This combines Sonic’s signature grilled cheese sandwich on Texas Toast and slides a burger patty in the middle along with ketchup, mustard and diced onions. If you’re really hungry, you can also order it as a “double” (with two beef patties).
It’ll run you less than three-bucks and arrives on menus starting September 26th and to make things twice as as nice – if you order online or though the Sonic app, they’ll score you a BOGO – buy one and get another for half-price.
