The employee working the register had to check with the rest of her team when I asked if I could get all of my toppings on the side.
She said an extra bun isn't something they usually give, but that they would let it slide this one time. I looked on my receipt and it wasn't listed on the ticket at all.
A regular cheeseburger cost me $9.39 at my New York City location, while a little cheeseburger would have cost me $8.19. If you split the cost of the double-stacked sandwich after dividing it, you'd wind up with two burgers that each cost $4.70 — a huge deal at Five Guys.
In my bag, I had a tray with pickles, lettuce, tomato, and onions, a separately wrapped toasted bun, and then a third tin foil package with my cheeseburger. I also asked for my sauces on the side, so I had two separate plastic containers of hot sauce and barbecue sauce.
