We have a real weakness for Japanese food and have previously mentioned Kibuka, which is one of our favourites. On the recommendation of some friends we recently visited the Japanese restaurant Can Kenji and have since been back a few times. Now we have never actually been to Japan but we suspect that this place unlike many other "Japanese" restaurants is the real deal. This is based on the fact that they serve some rather unusual stuff and that the place is generally full of Japanese/Asian guests. This is the first place that I have seen raw horse on the menu (Tataki de cavall), which is in fact delicious, or vegetable based desserts with potato and beans.
Now these dishes are some of the more unusual ones and there are many less experimental dishes. The sushi is served the traditional way here and is a good option if you feel like playing it safe. The quality of the fish and rice is excellent - perfectly made and served! The dishes are relatively small so we would suggest that you stick with the Barcelona tapas concept and sample many dishes when you visit Can Kenji. The place is reasonably priced and table reservation is essential as it is always packed. DC!
