Back by popular demand, Sonic's beefy and cheesy Grilled Cheese Double Burger is once again being served up at Sonic Drive-in for a limited time.
This substantial Sonic burger begins with 2 pieces of crispy and buttery Texas Toast that are then packed with 2 slices of melty cheese, 2 seasoned beef patties, white onions, ketchup and mustard.
The Grilled Cheese Double Burger will be available at participating Sonic locations while supplies last.
