Just a hop, skip and a jump from the Pope's house and Vatican City is a trendy little sushi restaurant called Zen. Like Hamasei, Zen has both table seating if you come with friends or if you choose to dine alone, you can sit at the bar near the sushi chefs. Zen was the first sushi restaurant in Rome with a conveyor belt where diners can pick and choose their rolls, sashimi or other goodies as fast as the sushi chef puts it out there. Zen is definitely one of the top notch sushi restaurants around town which means you will pay a pretty penny here. It's a well heeled crowd here and a bit hoity toity. While the portions aren't as big here, rest assured that all of its plates are full of flavor. METRO: Ottaviano. BUS: 81, 492.
