SonicCustom Burgers topped with anythingBurgerAnythingAsk if you can have a burger be "Made-to-Order" from the Sonic Secret Menu. The staff at Sonic's has a variety of sauces and toppings that can all be added to your burger.All Locations5 - Medium-HighVaries by Locationhttp://hackthemenu.com/sonic/secret-menu/made-to-order-burgers/The "Made-to-Order Burgers" options at Sonic are quite impressive. This Sonic "secret menu" option is hardly an option at all, it leaves your burger up to whatever your imagination (and stomach) can handle! What you see on the traditional menu is just a small fraction of the ones they make. There's the Dixie Cheeseburger, the Thousand Island Jr. Cheeseburger, the California Cheeseburger, and the Super Sonic Jalapeno Cheeseburger, to name a few. If you'd like a burger that's not currently on the menu, just ask. They probably have all the ingredients on hand needed to make one of the secret menu items so have your burger made-to-order.
