Burger 21

I tried this place last week because I have been curious about it for quite some time and I absolutely loved it!

I got a BBQ bacon cheeseburger with some fries and a Chocolate Milkshake, my burger was cooked medium well and it was ABSOLUTELY DELICIOUS!! It had to have been the best cheeseburger I've ever tasted in the Washington DC metropolitan area, The fries were also great and my Milkshake was ABSOLUTELY delicious 😋😁

They also had some really good dipping sauces to choose from, if I had to recommend my favorite one it would be the Thai Keptchup, it had a good sweet and sour kick which was great with my fries!

Service was pretty good and the interior and Restrooms were clean as well

This location is also a very short walk to the Ashburn Metro Station which makes a great option if you want to take the Metro here!

The only con I had about this place was that it was a bit overpriced, but the quality and the portions you are given, it's worth it 😁😁

Overall a burger place I recommend if you are in the Ashburn/Washington DC Area

Burgers are pricey but for a reason. They are very different from the chains. The beef burger was good. Hawaiian burger was awesome. The shrimp burger was the best. Must try. Somehow the fries were slightly soggy. Cheerful service. Strictly following social distancing.

Best burgers ever! I mean WOW! They were juicy and fresh. They had more sauces than I can imagine. The sweet potatoes fries were tasty too.

Thai shrimp burger and Santa Fe salad are our favorites. Kids loved buffalo chicken and barbecue bacon burgers. Definitely our favorite burger place.

My fiancé and I get the big cheesy and the bean burger with shareable fries... and let's just say it never fails to deliver the deliciousness... not to sound cheesy, but it is by far the best burger with cheese around here... don't forget the milkshakes... ask for peanut butter... you won't regret it.

Everything was great! Burgers were juicy and delicious. Service was great. Thanx Matt for a great experience. Will be back

Shrimp burger was good and so was chicken montery. Loved the Oreo milkshake.
Onion strings were OK, not crispy and salty.

Great experience here. They made a shake that was at first not satisfactory but Nelson and Narcos actually created another flavor shake and were so kind and mannered.

Wow! Fantastic burgers- juicy and delicious, seasoned just right, cooked perfectly to three different temps for our table. Fresh, crisp fries that are like "the golden arches" shoe string only fresher. Friendly, prompt service from Willie and Carlos. Bia delivered knock-out milkshakes for the kids. Clean, well-stocked, well-lit burger stop with enough unique sauce choices to warrant frequent dine-ins. Hand washing station a major bonus with those burgers, fries and kids. 5 Stars! Must try!

The food is absolutely delicious. They have vegitaian veggie burgers such as beyond meat and black bean burgers. The fries are out of this world too!! The place is clean, the staff is friendly, would highly recommend :D

First of all congratulate the members of burguer 21 who are behind a metal door preparing a delicious hamburger, regardless of whether you are a vegetarian or a child or a grandfather prepare a rich hamburger as you ask. Is a very welcoming place the owners are very interested in improving the products and every time they have a wide range of fresh products to take to their customers. Have a fantastic staff that takes your tastes and desires to a rich and juicy hamburger or any product present in the Menu. The salads are fantastic, very well presented and with the requirements that the client demands without leaving behind the fantastic sauces that seem magical. The delicious tenders that are crunchy on the outside and very juicy on the inside accompanied by sweet potatoes is fantastic, the shakes are very creamy and I assure you that you will want to try more and more. I recommend having a little patience when the restaurant is a bit crowded, as sometimes we are critical of saying that our food will be delayed. But I guarantee that the operations so that you enjoy a delicious hamburger as we do not deserve it is being elaborated by the best hands and the best people so that your family and your body are happy and satisfied with one of the best hamburgers that for me are The best I've ever had in my life and in my travels in the United States. I am very grateful for its owners and other people who made possible my stay in the restaurant for a huge attention with me and my family, fulfilling an excellent menu. A hug and bon appétit

Great burgers for a fast food place. The area is nice, we always eat here before going to the movies. It is a family favorite burger place. The fries are just perfect. Many sauces to deep and experience. I am now a regular.

tex mex burger is my favorite burger. Consistent everytime, 5 stars would definitely recommend

Really good burger and fries, very over priced but inflation lol honestly it was good but I will not pay 20 bucks for a burger fries and drink again.

An impeccable attention from the entire team. the quality of the hamburgers 100%

We always go as part of our tradition of playing a few rounds of laser tag over at the Zone, and then winners get milkshakes.
The food is really good, and the 21 sauce is solid as well. They even custom made me a milkshake that had been taken off the menu earlier.

Best burgers in town. Scratch that, in the whole NOVA region. I love their burgers. My wife do not like the buns so she always gets the lettuce bun and she loves it. need to try impossible burger next I am there.

Best Burger Shop Near Ashburn, I would go there everyday if it was healthy.

I always love to go there because of their burgers 🍔 and milkshakes
Espresso milkshake is my favorite

Burger tastes great. Love their multiple selection of sauces. Prices are amazing as well. I hope it stays this way. Cashier was very friendly as well.

Try their Wednesday Cheeseburger menu option Combo that comes with free fries!
