I had never been to Five Guys before this visit. When I went into this store the first thing I noticed was the music. It was too loud and it made me want to turn around and leave immediately. The cashier was obviously done with his day and just wanted it to be over. They took my order, and I need to say $22 for a burger and a small frie with no drink is asinine. They were relatively quick to get me my food, but it wasn't fast enough because holy crap did I want to be anywhere else. Overall, I'm never going back to a Five Guy's. Partly because of the general atmosphere, mostly because the prices are insane.

What is the Five Guys story/How did you guys get your name?
Five Guys began its pursuit to redefine the global burger landscape in 1986 when Jerry and Janie Murrell asked three of their sons whether they wanted to start a business or go to college. 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.

Does Five Guys offer gluten-free options?
The only products we offer that contain gluten are our buns, hot dogs (Canada only), HP sauce (UK only), and the malt vinegar condiment for our fries. In Canada, our Poutine Gravy condiment also contains gluten. All of our sandwiches, including burgers, hot dogs and the veggie sandwich, are available without a bun via our wrap or bowls.
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.
