I was a big fan of Five Guys - when I was on the East Coast this was the best.
However, lately I've been ordering burgers on lettuce leaves and this was by far the worst one I've had. I asked the cashier if they could wrap the burger in lettuce leaves (like In-n-Out does so well) and what I got was a foil packet with my meat, cheese and mushrooms on a bed of chopped floppy lettuce with more thrown on top. Yuck! There wasn't a nice crisp piece of lettuce to be found.
