“ Loved that I could create my own pizza via the app; down to which half the toppings were on and how to cook and cut it. The pizza arrived earlier than the estimated time (on a snowy night, no less), plus you can't beat free delivery. The delivery driver was friendly, calling first to let me know he was here and ask about the best entrance. Bonus: I got coupons for my next order with the delivery. Everything was prepared and cooked exactly as ordered and very delicious. Will definitely be ordering from here again in the future! ”
“ I came in 26 minutes before close and was greeted straight away by Kai. He seemed happy to see me despite being nearly closed up for the night. The staff was friendly and could tell they work well together. I had 3 slices, supreme, Hawaiian, and plain cheese... with a DrPepper (not pibb!). The slices were warmed up to perfection. The crust is great and the “thickness” of the pizza was spot on. Delicious slices for sure! I’ll definitely stop by again when I’m in that part of town. Thanks again Kai! Made my hungry self ultra satisfied. ”
“ Excellent and quick. The pizza slice is huge, hot, and delicious. Customer service was wonderful. Prices are reasonable. This establishment is clean as well as the bathroom. Recommend this location. ”
