    Pizza With Vegan Cheese and roasted / heirloom tomatoes
    Chris H.

    This place is outstanding - criat is chewy and just a touch charred, perfect... Great sauce, high-quality toppings, cooked right... They even have vegan cheese, which was fantastic, you can see that on the tomato topping pizza here. Best in Ashburn

    This isn't going to be popular. I really wanted to love the pizza but one pizza was burnt. The other was borderline burnt. The pizza was also tough. There was some good. Delivery was FAST. Flavor was good. Options plentiful. Overall a disappointing experience. Will I give it a try again? Likely not, we have many other choices.

    The ambience was pretty cool. I think the coolest part was it was connected to a ice-skating rink so when you go to kids practice or they're having a game, you can stop there and get something to me which is very good service. What's good nothing is wrong with this service now I got the buffalo chicken pizza. I believe that's what it's called. The only problem I had with that was more onions on it than chicken. It really tastes like I was eating a onion pizza meat. I don't need that mini onions so I didn't work out that well for me the other half and love those.

    Pizza shop at the ice rink, and they didn't have any unsweet tea for me, but the pizza slices were popular with the kids - and Italian coffee shop inside it, too.

    I'm glad these guys are here. They seem pretty passionate about their pizza! It's convenient to grab dinner pizza while my son is at practice. I tried two different slices and both were great. I loved the crispy crust. A lot of times pizza with more than 1 topping will flop but not these. I'm excited to try the other varieties.

    Buffalo chicken pizza and ricotta cheese pizza

    It's been my dream to find a NY style pizza shop in the area, and THIS IS IT!!! Stopped by today and it's the best pizza shop in Nova!! I got slice with Ricotta cheese and buffalo chicken pizza slice with sprite... all for $10 (lunch special)!! I was mind blown by the taste and price! The owner was super friendly! Thank you for opening this place!

    FUCKINGGGGG TERRRRRRIBLE, NEVER FUCKING AGAIN DO NOT EAT HERE UNLESS YOU WANT STAPLES IN YOUR PIZZA!!!! We ordered from Grub Hub, with it being sealed and opened it up with Staples all over it, called the manager and he acted like he didn't know how it happened and blamed the driver.

    Pizza was very good compared to the chain garbage in the area. A hidden gem for sure. My kids also loved it

    Pizza was very good, particularly the crust - nice and crispy and chewy.

    We had Pizzeria Moto at a party for my son's baseball team in the spring. What an unexpected treat…read morethis turned out to be. The pizza was incredible. The dads could not get enough of it. I like my crust to be thin, with a bit of chew, and Moto's was perfect. The toppings were great, but it's the crust that makes a superior pizza and Moto's is spot on. Plus, Jay the pizza guy was very friendly and happy to answer any and all questions. I would not think twice about using Pizzeria Moto to cater a party at my house.

    We hired this vendor for a private event and paid the requested deposit promptly. Two days before…read morethe event, we were suddenly asked to pay the full remaining balance plus full gratuity before any services had been rendered. The explanation given was that he had been "burned" by previous clients, which frankly isn't a professional or transparent way to do business. If full prepayment including tip is required, that should be clearly stated upfront, not sprung on clients days before an event. When we raised questions about these last-minute terms, while juggling other commitments, the vendor abruptly canceled on us and refused to refund our deposit. He claimed we never returned the signed contract, even though communication had been ongoing for weeks. Between the disorganized billing, poor communication, and last-minute cancellation, we left this experience feeling taken advantage of and deeply disappointed. We would not recommend this vendor based on our experience and lack of trust in his practices.

The Don's really impressed me, and I already know I'll be craving their pizza after work. The atmosphere: It's located in a quaint area and has both indoor and outdoor seating. The food: My partner ordered the White and Hawaiian slices, while I went with the BBQ Chicken Man and Sicilian Hit. He also raved about their combo deals, which are such a great value. One combo includes two specialty slices and a fountain drink for $8.50, and there's another with two cheese slices and a fountain drink for $7. I also loved the selection of toppings available at each table. They had parmesan, a blend of pepper flakes, oregano, garlic powder, black pepper, and more. Pretty much anything you could want, they had. The pizza itself was delicious and filling. The crust was the perfect thickness, and they definitely did not skimp on the toppings. The service: The staff was friendly and speedy overall, no complaints.

Sometimes they are nice enough to add toppings to already prepared slices. Most of the time I hear that they only offer those that are already prepared. REALLY?? Who does that? I am done.

The Calamari (fried) was pretty good, and there was some fried zucchini in the mix. Cooked to perfection. They offer garlic bread... It looked like half a ciabatta loaf, and to my surprise, it was covered in mozzarella cheese (melted well in the pizza oven) not used to garlic bread covered in cheese, but it was a pleasant surprise and very good. The entrees were passible; however, the Veal dishes were not as tender and enjoyable as they should have been. They need to tenderize the veal properly before preparation. I thought there may have been a bad piece, but all three veal dishes garnered the same complaint. I am a veal snob from NYC, so proper meat prep is a must for this dish. (Happens in other Va Ital restaurants too.) The chicken marsala was good with no real negative complaints. The only thing I can say is that for the price charged, a larger portion would be a better model. When the plate looks sparce when they put it on the table, the impression is not a favorable one. Now that being said - The deserts are huge. Perhaps to offset the meal size. Tiramisu could feed two to three (with extra spoons supplied). Cannoli were pretty good - expected one and received two fairly good-sized cannoli on the plate - took one home. Will give them another try at some point. Maybe the Father's Day rush limited performance. We'll see.
