Slightly above average pizza. Although no tap water guys ? Would reconsider as it costs you near nothing for the convenience of customers.

Otto’s has delicious pizza, the best around in my opinion. The slices are very generous. The ingredients are all high quality and yummy. My go-to is the ricotta with basil slice, but I’ve tried many of their inventive combinations and have never been disappointed.

Absolutely fantastic experience by Rina and all the women working! The Pesto-Roni is a walk off home run in the bottom of the 9th. Mashed and bacon very good as well but hands down Pesto-Roni kept me in the game!
