Awesome buffet. Quality and diversity of food is great, well-maintained throughout the day, and half-priced after 3pm. read more

I've been a regular at this place for almost a year now. And the relationship between me and this business had ended with the store owner physically assaulting me that ended up in a police report. This morning, I've ordered a breakfast sandwich online. When I came in and picked up my order, the egg was overcooked and dry so I requested that they make me another one. The female owner was visibly displeased when I requested for another one, then her husband came out, stood there and just looked at me and had asked me to leave. I replied, "Why are you asking me to leave?, What did I do wrong?" There was no explanation. At that point, I couldn't believe what I was hearing. So I too became frustrated and ended up tossing my sandwich onto the ground. He lost his cool and then violently dug his hand into my chest and grabbed my shirt from the chest up and demanded that I pick up the sandwich for him. One of the store employee had screamed at him to "STOP!". He kept on grabbing me , so I shoved him back to protect my self and left the store. So I decided to place a police report after being assaulted by the male store owner and was injured as a result. There were obvious scratches on my left chest. This store owner had no right to touch me, regardless. But we'll let the court decide on this case. I would strongly advise that you do not come to this place. These people seemed very nice at first but some reason, this happened. read more

This a nice family run place. As other reviewers have said, it is a pay by the pound food bar. They have breakfast in the morning and lunch in the afternoon. They open early and close at 4:00 PM. They have a pretty extensive salad bar and a nice hot bar. The salad bar is cleared out of any lettuce (spinach, romaine, iceberg, greens) by around 1:30 PM so come early if you want that. They also have two folks working the grill in the back to make sandwiches, subs and gyros (the latter only on certain days). They have good lunch specials as well. The people are nice (Cookie is the one of the girls up front--very nice and good service). They also offer a frequent customer card. You get a stamp for every $6 you spend and once you get ten stamps you get $6 of free food. ALSO: They now accept credit cards. read more

Staff were friendly & professional. Breakfast was fresh & yummy. Coffee & tea are good. Prices were fantastic.

This place is delicious. The food is fantastic and reasonably priced for the area. The coffee is hot and fresh. I am always greeted with a smile and hello. Ask them about their frequent meal card! read more

Good breakfast or lunch option. Good coffee. Priced about like every other downtown lunch spot. Diverse veggies and meats and low carb options for the sandwich-averse. Two improvements could be easily made: 1) Leave the half and half out at lunch or at least include an unsweetened creamer option. 2) List known allergens - The chicken/tofu dishes look great, but wheat? No wheat? read more

"Hi, can I get the [sandwich that comes with chicken breast and many other delicious things that I love]?" "No. We are out of chicken breast." "Oh, well can I just get it without the chicken breast?" (That's how much I love the other stuff.) "No." "Wait, you can't just make that sandwich, but just not put the chicken breast on?" "No." Okay then! Bye forever, Cornerstone. read more

This is that kind of fast food place that reminds me of Korean-owned cafes in college food courts. You come here to grab a bite on your way to work because you couldn't get up early enough to have a proper sit-down breakfast at home, or a sandwich for lunch because, well, who has time to eat lunch anyway? The breakfast bar and the buffet are pretty typical. I find most of the buffet items a bit too greasy, even the toast. But there's fresh fruit you can help yourself to. And it's not cheap, either - but compared to Whole Foods a whole lot better. It's so hidden that even after having resided in the very same building for three years, it didn't dawn on me it existed and that I should try it out. Compared to Peet's across the street, it's definitely got better real food (no I don't want to pay $6 for a sugar-laden scone that doesn't give me real nutrition for a meal) and reasonably priced coffee. I once paid nearly $20 for a pound of ground coffee at Peet's; it's good, but definitely not five times as good as my everyday cup of joe that I can get from a Dunkin or regular cafes like Cornerstone. read more

I've been to the cafe twice. I got an upset stomach after the first time I visited but was not certain the food was the cause. I went back again and when I was near the salad bar, I saw a baby mouse racing around the floor. I told an employee nearby (who used the rag he was cleaning the food surface with) to grab the mouse. He was very calm about it which made it seem like this was a common occurrence. Needless to say, I didn't buy anything and won't be returning. read more

While looking for a quick and inexpensive meal, walked right by this place and decided to take a chance. Although I'm not a fan of buffets, this place was very clean and the food was hot and fresh. My meal,a bottle of water, and some juice rang up for just over $10 which I thought was an excellent price for downtown D.C. I heard breakfast is great, so I'll probably be back later this week for that! read more

Cornerstone Cafe - Just a Lil bit of everything. - Bagels Near Me - Washington, DC, District of Columbia

I would seriously be lost without this place. I work kiddy corner to it and go there at least once a week either for lunch or breakfast. Both are great. The buffet has everything you could ever want. The food (almost always) looks fresh, it -always- tastes good, and they have seasonal stuff. They also have a coffee bar, a sandwich station where they'll make you any deli sandwich you can think of, and even have some new ones, a huge fridge with almost any drink you could want (seriously though, where's the blood orange san pelligrino?!), and a wall of munchies. They DO take credit card and cash. Don't trust the baked goods at the front though. Stale as all get out. read more

Great weight bar restaurant located near work. They offer a punch card & after 12 visit you receive $6 off! Hot bar menu changes every day which provides a good variety and very tasty food. Excellent customer service and always clean. The owners are wonder and work the restaurant preparing food, cleaning and interacting with customers all day. I probably visit 3-4 days a week! read more

This place apparently had pay by weight hot bar but removed because of pandemic, so now they have prepackaged asian meals that are quite extensive--beef bulgogi, rice, shrimp, sweet potato noodles, steamed vegetables, omelet, etc. Or you can get a hot or cold sandwich made to order. There is indoor dining, but it looks like they never bothered to take the chairs off the tables or separate the tables, so the tables are all jammed together and still have chairs on them, which you have to take down yourself. I think they canceled indoor dining for a while and just started up again, but forgot to take down the chairs when they started up again. It's annoying and does not make for a welcoming experience. I shouldn't have to take chairs off tables and separate tables before I start eating. Hopefully the salad bar and hot bar will come back soon. They give large portions, enough for 2 meals. read more

Good place to grab a bite to eat on a budget. This place offers a breakfast buffet which allows for a variety of foods in a quiet environment. Quality of food is not best but still worth it read more

Just moved to DMV from NewYork. Ive been to alot of places in new york but this place is the best. Clean, good quality foods, friendly staffs. I definitely recommend this place. Two thumbs up!! read more

Let's start with very clean and organized for a breakfast and lunch buffet. When you walk in everything is in front of you. If you are a picky eater you will find something you like, and if not then pig out. No servers, just self serve and you can also have food made to order. A few different flavors of coffee, juices and teas. Small dining area but it is not for patrons to spend the day in the establishment , only to be in and out. Only reason I give a 3 star is the friendliness. Not much talking between patrons and employee and they are only open during the week! Enjoy!!! read more

So many Asian cuisine, I like this place, I can eat delicious foods and enjoy good service, nice.

DISCLAIMER: This place now accepts credit cards - as another Yelper mentioned it used to only be cash. I go to Cornerstone every day for lunch and sometimes breakfast. This market serves up high quality at a very reasonable price. The clerks are very friendly and efficient throughout the rushes and I'm always sure to see something I like. Try the chargrilled chicken (korean style), baked salmon and salad bar. On Friday's they have a new item - a rockin Thai Curry seafood medley with HUGE mussels. I was just at a French bistro in midtown yesterday and their mussels are weak compared to what I just had today at Cornerstone. Check this place out. read more

Great breakfast buffet. Cold and hot items as well as ready-made. Always clean neat with very friendly service!

Still affordable breakfast exist inside of downtown DC. Thank you. I don't like spending 15-20 just on eggs.

Very disappointed. The lady doing breakfast sandwiches can barely speak English and totally ignored us. We were pushed aside for other customers (Thursday 8am / 8-20-15). Besides, the do vegetarian sandwiches on the same grill as meat sandwiches. Ate from the buffet and the food was mediocre. Wouldn't feed a homeless person there. Who is mismanaging this place? read more

Good food bar fare for a work-a-day lunch if you're downtown. I like the food bar concept as one can load up on the proteins and greens and skip the carbs. They have a frequent customer card that gets one a nice discount after a few purchases. The problem with food bars is that if you go in hungry, you'll tend to load up and then pay for your lack of restraint at check-out, as the food bar stuff is all sold by the pound. There's outdoor seating for nice days, and enough indoor seating to be able to eat alone without feeling like a freak. read more

Solid food. I usually go to the grill, but I've tried the buffet a few times, and enjoyed it. The grill food can be a bit greasy, such as the reuben. I love a reuben, and want to taste everything, but usually it is too greasy for me. But the burgers are good, and the grill workers are super friendly. read more

Great little spot. Was in town for a conference and I ate breakfast there every morning. Good selection of breakfast items, fresh fruits, and salad bar. Cashier, cooks and staff were all pleasant. Great bargain for breakfast. read more

With prices raised to $6.99/pound, the food isn't exactly a steal. But Cornerstone does offer ample variety, a fresh salad bar, and truly devastating mac-n-cheese. read more

Good place for a salad, if you are smart to not pile on the heavy items (watermelon, fruit, hard boiled eggs) it comes out to a good price. Also you can get a bite or two of chinese or whatever else to add a savory morsel as a side dish to your salad. Sandwiches tasted good and are fairly priced. I come here multiple times a week. read more

Great breakfast sandwiches and cheap espresso drinks, plus everything else under the sun. The staff are so friendly--they always remember your name and your order, if you're a regular. Definitely worth a trip. read more

Very good service. One time I left some very important papers on my table. The staff caught this and gave my stuff back to me that I had completely forgotten about, even though this is only a buffet. I wish that the servers at full-service restaurants were that attentive. read more
