Known as Visa-O1 when it opened in Miami Beach in 2014, this pizza joint had to tweak its name owing to trademark issues. The "O1" is a reference to the O-1 visa the U.S. reserves for "individuals with extraordinary ability." So, yes, this pint-size pizzeria thinks highly of its pies — and with good reason: Only the freshest ingredients and premium-quality cheeses (vegan cheese is available for an additional charge) are allowed to top these thin-crust pizzas. The signature pie, the "Star Luca," is star-shaped, its points formed from perfect little dough pockets filled with creamy ricotta cheese, its center layered with the house Italian tomato sauce along with mozzarella and spicy salami. That stellar creation set Mister O1 apart from other local pizzerias and led to the concept's expansion to several other locations, including Brickell, Wynwood, and Boca Raton, not to mention Madrid, Saudi Arabia, and Naples (Florida, that is).
