    #71 Steakhouse Black Pepper
    Ritvik N.

    Juicy burger joint sequestered in the heart of Loudoun Station. Buttressed by Blackfinn Pub and Famous Toastery, a solid go-to movie theater right around the corner, and the brand spanking new metro station in Ashburn within walking distance. I came around noon, debating on brunch at FT or a quick-and-easy lunch at B-21, my fave local spot to grab a burger at. I decided to cast caution to the wind, and play shotgun roulette with B-21. I swung by here, and was presented with a near-deserted ambiance and a non-existent line. This place sorely needs more patrons, if you ask me. I rolled the 20-sided dice yet again, and went with the Steakhouse Black Pepper (#71) -- a limited time burger, and a likewise signature shake to go hand-in-hand with it -- the Triple Shot Espresso. At the end, I was presented with one of those fancy flag things that flagrantly flew my order number -- #69. Right on, brotha. I would've preferred a digit higher though -- almost hitting the nail on the head, my fave number knocking right next door. Wait was not bad. I chose one of those fancy, four-seater booths adjoining the window. Milkshake arrived first, with presentation on top-tier level. Black, chocolate-coated espresso beans with what looked like cinnamon sprinkled atop it. I had a few sips, and it truly hit the spot, on what felt like the warmest day in the cold, biting heart of Virginia winter. The burger arrived later, shadowing the footsteps of the shake. Luxurious angus beef patty, Swiss cheese riddled with miniature holes that would even make a mouse proud, smoked bacon that skirted the edge of grandeur, and a brioche bun that provided the fitted icing on a medium-rare and well-seasoned cake. While I ate and drank my milkshake in the warm and languorous peace, I thought about my experiences, life choices, and a little of everything. I appreciate the peace that the atmosphere offered me, on a deep and altogether personal level. Burger, pretty solid and a home run in terms of presentation alone. Milkshake, never tried but a signature and unforgettable flavor. All in all, solid experience at B-21. Burgers here are reasonably priced, and have never let me down so far.

    $41 for 2 burgers, 2 fries and a tip is A LOT! But they were good. We got the OMG burgers w/ egg and the shared fries, half regular, half sweet potato. We tried the apple cider and toasted marshmallow sauces as recommended with the sweet potato fries, and DAMN! Perfect complement! They're definitely made to order, so be patient. They don't take terribly long, but it's not fast food fast, either. Enjoyed it!

    Great customer service and was very helpful and kept the place clean. Menu is simple yet decent and has awesome options. I ordered the sliders got the shareable fries which is still A LOT for just two people. They have a huge selection of sauces for your food and I was amazed at how good they actually tasted. Normally, places that have numerous sauces have a lot that are just "ok". B21 all except one tasted delicious and my favorite was the Thai Ketchup!! Definitely will return to try the milkshakes and sweet potato fries.

    Kid cheeseburger and fries

    Probably should not have ordered a salad at a burger joint but c'est la vie....my son and I stopped in before going to Christmas Village at Leesburg Animal Park. It was a Tuesday around 5:15pm and it was pretty empty. Order at the counter,pay, and they bring out the food. My son had the cheeseburger kids meal with fries and an Honest berry lemonade. He ate all the fries (which I vouch were tasty), but his burger was on the burnt side. My salad left a LOT to be desired. It had no nuts on it or romaine lettuce as noted in the description. It was all iceberg and very little goat cheese. The chicken was cold and rubbery-seemed like it came out of a Tysons bag. The one thing that was good was the sauce bar. The spicy Thai ketchup was delicious. I probably would not return based on this visit if I were in the area. Should have gone to chick-fil-a.....

    We have come to frequent Burger 21 to enjoy one of the best hamburgers in the area. The staff at Ashburn are friendly and we our experience every time. Highly recommend.

    Awesome burger , tons of sauces and a great feel to the place . Service was quick and friendly . Clean inside and staff quick to pick up after customers were done .

    Came here on a Wednesday to get their burger deal! It is $8.99 for a burger and fries which were honestly both delicious. They also offer gluten free buns and an entire row of different sauces to try with their burgers and fries.

    Sweet Potato Fries
    Judy N.

    I'm not a burger fan so I seek alternative options when I eat at a burger joint. Their chili cheese dog is darn good and the Thai shrimp burger is lightly breaded, tasty, and has "umami". The place is family/kid friendly of course. Which kid can say no to sweet potato fries and sliders? Not mine. She loved her cheesy sliders, with the sweet potato and string fries combo. There is also a kids menu with salads, hot dogs, grilled cheese, and chicken tenders. I think what wow'ed me were the variety of sauces. So many to choose from! The Cajun and Thai ketchup were my favorites. I ordered the hazelnut chocolate shake and I didn't like it. The pictures of the huge toasted marshmallows fooled me. If I return, I'll probably try the strawberry or Oreo shakes.

Crispy on the outside and creamy on the inside. There was a tomato dipping sauce on the plate which was very tasty. My only criticism is that the Mac and Cheese needed some salt. The Brussel sprouts were cooked in balsamic vinegar. They were cooked perfectly and absolutely delicious. The onions were a nice addition to the plate. We both had smash burgers. Mine had the fried egg on it and my wife's had BBQ sauce. The burgers were wonderful. Very tasty. Possibly the best smash burgers in Loudoun County. My only critique is that the meat itself needs more seasoning. My tater tots were nice and crispy, although they weren't hot, only warm when our plates came out. Our server was wonderful. She came by our table often to check on us. I would definitely recommend this restaurant. I highly recommend the Smash burgers.

We have tried…read moremany of the restaurants in Ashburn but have ended up at Original Steakhouse for a host of reasons. Their kids menu is adequate and he can always get kid-friendly food that he wants. The little guy is very picky and eats like a kid and OS food works for him. He especially likes the hot sweet dinner rolls that we always get before the meal. The atmosphere is great in the bar. I've been going to OS since it opened as "All-American" long ago (under then questionable ownership). The bar with projectors showing sports all around you with a large traditional bar in the middle with plenty of taps is a great room. (ASIDE: I always found it odd that they installed 4:3 aspect ratio screens and it is mildly annoying that all the TVs are stretched. Just show the HD with bars on top and bottom please. Stop with the stretching please!!!!) The prices are fair and low. They always have specials and have a great happy hour special that lasts longer than most of the competition. We can get out of there with two good meals and ice cream for the little guy for $10-15 less than even the cheap local chain restaurants! PLEASE keep the place affordable - going out to eat is SO EXPENSIVE in Ashburn and I dislike fast food; it's really nice to have a good sit-down restaurant where I can get a beer and my son can get a Shirley Temple and both of us eat a good meal for under $50.

Then another 10 minutes came the steak, they initially gave me a baked potato instead of a sweet potato initially but they fixed it quickly upon being told. The steak was cooked to a proper medium temperature. My strip had good seasoning, however the quality of it kinda tasted a bit cheap (not much marbling). Service was kinda bad with the waiter not checking up on us and waiting over 15 minutes to get the bill even though it wasn't that crowded. Overall I was not blown away, and perhaps a bit disappointed with the quality and taste. Food(50%): 5.2 Staff/service(25%): 5.0 Value(25%): 6.0 Overall: 5.4/10

For dinner I was between a couple of items, but I rushed myself to order the Steak and Cheese. When it arrived it appeared that I received the previously mentioned "steak tips" sandwiched between bread, with some condiments and cheese. Maybe I should have read the description a bit more carefully or maybe I expected something more typical of a Steak and Cheese. I did want to order the steak tacos after both, just to see if they were the same. Someone please let me know. I understand that restaurants will utilize ingredients across multiple dishes but this just seemed ridiculous.
