Z-Burger is a small DC burger chain located at 3301 14th St. NW in Columbia Heights, with additional locations in Tenleytown, Dupont Circle, and Virginia Square, Arlington. The format is similar to Five Guys, another, older homegrown chain that has grown far larger. Burgers are grilled fresh for the customer and you can choose from a wide variety of toppings for no additional charge. My burger was certainly tasty, though I found the patty slightly less juicy than Five Guys. It did hit the spot, though, and it wasn’t as if I tried it in blind taste test up next to Five Guys- that would be possible given how close the nearest Five Guys is, but I don’t think your nutritionist would recommend it. The coolest thing about this Z-Burger location, however, is that it is situated inside the historic Tivoli Theater complex, which was built in 1924. As such, the interior of Z-Burger has a beautiful ceiling with crown moulding and antique, whimsical murals on the wall. It’s a cool space, and worth checking out.
