With more than 12 locations in buzzing cities across Florida, Texas, and even an international presence in Spain and Saudi Arabia, Mister O1 is dedicated to crafting exceptional and inventive Italian-style pizza using a delicate, thin and crispy crust made with a light dough. In 2021, Mister O1 was named “best pizza” in Florida by Food & Wine magazine. It received an impressive rating of 8.9 by Barstool Sports’ pizza aficionado Dave Portnoy, and its flagship location in Miami Beach is recommended in Florida’s MICHELIN Guide. The recipe for Mister O1’s success is simple - always focus on quality and consistency with both food and service, the hallmarks of Founder and Chef Renato Viola’s pizza. Launched in 2014 by award-winning pizza chef Renato Viola, the cozy, woodsy-chic pizzeria chain also features a burrata bar & fresh salads.
