When in Zurich, nothing beats a good Italian resto for lunch or dinner and San Gennaro is no exception! This is a Neapolitan pizzeria situated right by the Limmat river in Zurich. They have a classic Italian atmosphere and warm, energetic ambiance (the staff are Italian mostly too!) making it a great spot for a casual night out.
While the menu is rather small, but at San Gennaro, they are very good at what they do (I always rate a restaurant by how well they serve their simplest dish and here, the Magherita is amazing), so their specialisation is worth it. Prices are fair for Zurich's standards.
