I love going to Burger 21 for nearly every occasion. I always get a Bacon Cheesy and some onion strings, and it is always 10/10! The burgers are always juicy, and the service is nice and fast. I highly recommend their limited shrimp burger! It tastes just like a sushi roll.

We come here because we have layover for a night so we decide to get out of airport and eat.

Oh man, great place by the Dulles Town Center. Wide variety of burgers (beef, chicken, seafood, vegetarian) with different meats and combinations. Fries are potato or sweet potato. Drinks are either bottled or fountain. The hand washing station at the entrance is a clever and unique touch. Kudos Burger 21. Great taste, great customer service, great decor and ambiance. I expected a bigger burger for the price. Overall it was a good experience. I will be back. I strongly recommend. Good for the whole family.

Just visited for the Wednesday burger special, $9.99 for their cheeseburger with fries is a great deal, choose your temperature and make it happen! Everything is juicy and the fries are crispy, flavors are exactly on the money. We will be back!

Awesome burgers and wonderful service from happy people! Love this place. Don’t forget to order a side of sweet potato fries or onion rings. There’s also a great sauce bar with their secret sauce, ranch, apple cider vinegar and the usual suspects.

The burgers at this place are insanely delicious!! Considering I’m only paying a few more dollars for meal here compared to the “drive through” joints makes it an amazing deal to boot. The restaurant was clean, employed very nice, and exceeded my expectations. Would definitely visit again.

When they get it right, the food is an excellent value for the money. Unfortunately, over the last few months their attention to detail has dropped off and the food is suffering from it. 3 of my last 4 orders have had something not right, and when it’s a carry out order, it’s often not noticed until you get it home, making for a real hassle to get it corrected.

Ordered food for pickup. Food is consistently delicious and I love their gluten free options (Lettuce Bun is actually yummy). Wish they filled up my drinks for me when I came to get my food, the line for the drink machine was annoyingly long.
