I became a fan of pizza during my student years in the US. Pizza was the primary choice of students living on a tight budget. Going out during the weekend mostly meant enjoying Chicago style pizza with its thick layers of cheese, tomato and its rich toppings. Pizza, delivered to the dormitory, helped nerds satisfy hunger just take a break.
So pizza was the first thing to try during my first visit to central Europe in the late 80s. Groups of summer students would head for the pizzerias of Geneva, primarily those of the old town.
I was in for a big disappointment: Italian type pizza felt like a thin tasteless construct that cost thrice as much as the rich tasteful dish offered at the other side of the Atlantic.
20 years later, American pizza is no obvious winner of this “clash of civilizations”; thanks to the flagship of Italian type pizza that I have found in Zurich.
Pizzeria “Il Gallo” is not a tourist trap but earns its money from locals thanks to the quality of its food and service (and not with a location next to a medieval building). I recommend the “Diavola” (with spicy salami). In the summer you can eat outside observing a lot of car and human traffic since the venue is located at a going-out district with many cinemas, bars, clubs etc.
Go for a complete experience: start with a “Caprese di Buffala”; achieve closure with a Tiramisu.
