I really like Five Guys and I respect everyone when I go there so I would really appreciate it if I get some of that respect back. Today I went there and there is this lady at the register she was rude, rushed me the whole time, and gave the wrong order even though I told her what I wanted 3 times. Sorry, but I won’t eat there anymore .
Note: everyone else that works there is extremely nice and friendly.

Now, three decades after our first location opened in Arlington, Va., Five Guys – a fast-casual restaurant chain named for the Murrells' five sons – serves a classic take on hamburgers, fries and milkshakes in more than 1,700 locations across 24 countries.

While our crew members do all they can to avoid it, there is always a risk of cross-contamination. Please review our nutritional, ingredient and allergen chart for the most accurate information.
Is the Five Guys veggie sandwich a veggie patty?
Our veggie sandwich is not a veggie burger, but truthfully, it can be a mix of whatever you'd like. Choose any combination of our condiments and add cheese for an additional cost.
Our standard veggie is a mix of peppers, onions and mushrooms with or without cheese.
What is the best way to reheat leftover fries?
Leftover fries are excellent reheated in the oven (or Air Fryer). According to Chad Murrell, one of the Five Guys, just pop them in a 350-degree oven for about 10-15 minutes.
Also, give those leftover fries a try as hash browns, home fries, or even as the filling in an omelet.
