A complete evergreen guide to Five Guys catering for the office: how the burger bundles and boxes work, why Little and Regular are the two words that decide whether you over-order, how the toppings ride in separate trays and turn a drop-off into a build-your-own bar, what to do about the peanut oil before you order for a team with a nut allergy, how to keep the fresh-cut fries edible on the drive over, how much to order by headcount, how ordering works through ezCater or your local store, and where Five Guys fits against a local burger caterer and a managed platform for recurring team meals.
