Five Guys is taking over the world! Yeah, I know it’s a chain, but it’s our chain, a family operation that got started in Arlington 32 years ago. At last count, Five Guys had more than 1,200 of its joints in 48 states, Canada, and the U.K. You’ve got your hamburgers, cheeseburgers, bacon burgers, and bacon cheeseburgers, all of which come in two sizes; assorted hot dogs; a veggie sandwich and a grilled cheese for vegetarians; and your choice of regular or Cajun-style fries. One immediate difference between Five Guys and most other popular burgers, like D.C.’s Good Stuff Eatery, is the absence of a “magic sauce.” You do get to add as many as 15 toppings, grilled onions to tomatoes, for free. D.C. currently has nine Five Guys, including this Penn Quarter/Chinatown location.
