    Mozzarella sticks.
    Angela H.

    The pizza was very tasty. We also had Greek salads and mozzarella sticks. They were very fresh and yummy. You need to try the walnut pi bar with vanilla ice cream. I highly recommend you coming by and having lunch here. We were first timers, but if in the area again we will def return.

    Pizza is our go to post hike food and this makes a great post hike stop. My husband and I shared: - The 3.14 (large) - The Newton (small) Between the two, I think I preferred the 3.14, but I enjoyed both of them. If you're in the area looking for pizza, this is a good stop.

    First, let me just say that the food here was excellent! The 3 star review is related to the service/attitude, not the quality of the food. When we arrived we asked for a table for 4 and the young girl immediately said it was a 25 minute wait, even though there were a couple of tables paying their bill. There were also 4 seats at the bar, even though they needed to be moved to be together, but she said there was no seating available at the bar. Her attitude basically said "go away." Also, there's a sign that says "once you're on the wait list, you must wait OUTSIDE." And the menu says no 1/2 and 1/2 pizza, no substitutes, no slices. Again, they're not very welcoming or accomidating. That said, our server was very friendly and efficient. The food was delicious and the ambiance was great!

    Everything about this meal was great! The service was fast and friendly and I love the decor and theming...from the chemistry beaker chandelier, to the periodic table hanging in the bathroom. Very clean and modern! The star of the show, however, was the pizza. I had the Newton. The combo of the sweet fig jam, salty prosciutto, tangy goat cheese....it was perfection! My wife had the Papa Pesto which was also so delicious. The pesto was light but flavorful and of course the prosciutto was delish, cheese was melty and stringy. Highly recommend both! We live about 90 minutes away but we're already taking about coming back!

    So it's Saturday night in Clayton and the wait here was at least an hour. Be prepared to wait and don't think you can just walk up and eat. We started with the soup of the day. A squash soup that was amazing! So may autumn flavors. Next we had their wedge salad. It was ok but a little sweet for me. Next we had the mozzarella wheels. Delicious but can you really go wrong with fried mozzarella and a really good red sauce and theirs was delicious. Finally we had the 3.14. OMG. So good! We got a large so we can take some home. Delicious

    Great little pizza joint. We waited a bit for a table around 1:30pm on a Saturday but it was worth it. Service was fast and friendly. Local beers and ciders served here. We enjoyed the White Italian pizza. They also have a solid selection of menu items that are not pizza (salads, subs etc.) Owned by the same folks as Fortify, next door, which is a bit more of an upscale southern restaurant

    The small 314. YUM!

    I had lunch on two occasions here. Good service. AMAZING pizza. Some of the BEST pizza I've had in a long time!

    On vacation and decided to stop here. Food was great & service was excellent! Didn't take very long for us to get our food either! Definitely recommend the calamari!

    Excellent pizza. We were very, pleasantly surprised with the white pizza. Would definitely order again. Was kind of pricey

    The GF pizza is tiny and overpriced. Somewhat tasty but wish I had gone elsewhere for the money.

    Predictably yummy Caesar salad. Light and refreshing. Salad dressing is wonderful. Thank goodness Fortify Pi is in Clayton.

    This is a pizza hut classic location with seating inside. They have the 80s decor and pictures to…read morebring back old memories. For that alone it is worth the trip! Bring your jacket as it is freezing cold inside for some reason. Service was great. Kept the red cup full for the most part. They have a deep dish pizza, which must be unique to the classic locations. I love deep dish so I had to try it. It was ok but I will stick to the pan pizza going forward. We also had the garlic cheese bread.. Now that was delicious! Prices were good too. All in all it was a fun experience.

    Not a pleasant visit. We were the only ones in the dining room for quite a while. Chairs were out…read moreof place, and debris all over the floor, as well as the corner platform in the back. The salad bar was pretty sad, as the lettuce was limp and some brown throughout. The other items at the salad bar were old and not maintained. Our server, while initially warm, seemed bothered that we only ordered one large pan along with cheesy garlic bread. The garlic bread was simply tossed on a plate, one stacked on another, with bits of crust and cheese on the plate. No care whatsoever. The pan pizza was slightly underdone and the crust was dry. The server never checked in on us and spent a considerable amount of time outside on a cellphone. None of the tables had paper towel rolls and we only had the initial one napkin with utensils. Two other tables were seated and initially cared for, then the waitress went outside for a solid ten minutes. The cooks seemed to enjoy phone breaks outside frequently as well. The waitress showed some attitude to the wife upon seeing 15% tip. Not good. This will be our last visit until the management, owner, or corporate makes some drastic changes.
