More than decent sushi
We went there for two reasons: close to our hotel and, most of all, we trusted Zazie's recommendation. We were not disappointed at all. I would even say that everyday I like this type of Japanese restaurant a little more: you come in, eat wonderfully, and you go out of there with the sensation that you had a great time, with a very good service and most of all, without having to book nor wait in endless lines.
If you read guides of the best Japanese in Barcelona you won't find this one. If you just want to have more than decent sushi without having to go to the best one in Barcelona, this is the place for you. And on top of that, I discovered something wonderful: some curry noodles with something else I don't remember, which was really mouth-watering.
