In addition to the queso, the Queso Burger includes a quarter-pound beef patty, shredded cheddar cheese, grilled onions, and mayo on a toasted bakery bun.
To promote the new burger and their app, Sonic has an app-exclusive, one-time-use offer good for a half-price Queso Burger for a limited time through May 31, 2020.
