After reading several reviews on Yelp, we decided to give Rokko a try. The owner was very…read morefriendly. She speaks fluent English, Japanese, and Italian. We went on a Monday evening. It was one of the rare sushi places that was actually open on Monday. It was also quite warm in the restaurant. Admittedly, we were in Rome during a major heat wave, so maybe their A/C just didn't have the power to keep up.
As far as the rolls go, they had the typical sushi rolls that you find in most sushi restaurants. It tasted fresh and was pretty good basic sushi rolls. Maybe it's me or maybe my sushi has become to "americanized", but I like places that have specialty rolls. I like the ones that have spicy mayo sauce, or smelt roe, or avocado slices on top, or tuna/salmon on top, or spicy pepper, or etc etc etc. In my opinion, Rokko was simply basic sushi. Don't get me wrong. It was good, just basic.
Bottom line - Open on Monday (at least during the summer months). Good but basic sushi. I wanted more variety in the rolls. Personally, if I want sushi the next time I'm in Rome, I may try a different place first simply to see if they have better variety. If you do decide to try Rokko, I think you'll be treated well by the staff. They're friendly. Bon appétit.
