Just ordered for delivery and am terribly disappointed in the way the food came. Missing items burnt food and slimey lettuce. The bun on one of my burgers was completely burnt and the reason I imagine the bun was burned was because I asked for no mayo so instead of just getting me a new top bun they decided to try to cook it off which is not a fix but now I have burned mayo crust on my bun. Why not just get a new bun? This is my last time going to this smashburger.
