Vegan At
Five Guys

Five Guys is a burger-and-fries chain with a thin vegan ceiling. They do not stock a plant-based patty. What they do have: peanut-oil fries that are vegan and famously good, vegan buns (the standard kaiser roll is dairy-free), and a make-it-veggie order (no patty, all the toppings - lettuce, tomato, onion, mushrooms, banana peppers, A1, BBQ, hot sauce). The 'veggie sandwich' as a documented Five Guys order is a hack on the burger build, not a menu item.

What to watch forThe cheese on every menu item is American cheese and dairy. The bacon is bacon. The mayo is mayo. Of the documented sauces, BBQ is vegan, hot sauce is vegan, mustard is vegan, ketchup is vegan, relish is vegan, A1 is vegan, mayo is egg-based. The grilled mushrooms and grilled onions are sauteed in butter in some markets and in oil in others - ask. The peanut oil for fries is famous; the peanut allergen warning is also famous. The bun has not historically contained egg or milk but the recipe has been adjusted regionally; the scan re-verifies on each pass.

How we verifiedFive Guys publishes an allergen sheet for the bun and the fry oil that the scan reads on every refresh. The scan derives the veggie sandwich order from the documented topping list and pins the order script to the language a Five Guys cashier expects to ring at the counter. The grilled-vegetable butter question is the only counter-side check on the script because it varies by store, and the bun-formulation note carries forward as a recurring re-verification target across the whole chain because the recipe has been adjusted regionally in recent years.
