I had the supersonic breakfast burrito. Not much filling inside. I didn't get any meat in the burrito. It was mostly egg and potatoes. Very little filling. Not worth it. I might as well pay to eat at Jimmy's Egg. At least I'll get what I pay for.

Got two of the $1.99 little cheeseburgers and Derby location made them so yummy!
