my brother used to work for sonic. he said that they used to have tons of people order burgers with no buns, so many that they have a "no bun" button to push when taking the order. he said that when they first started doing them that way they weren't real pretty, he described it as "lettuce sliding all over the place" but they got better at it and they have always been very accomodating IMO.

I hadn't heard about the LC tortilla but that sounds cool, my mom loves their honey mustard grilled chicken wrap.
