Zen

There's no shortage of Japanese restaurants in this neighbourhood, but the recently opened Zen is refreshing in a couple of ways. First, there is no pale wood in sight; the colour scheme here is sharp white, green and yellow for a cheerful effect. Second, the menu has a lot to choose from - bowls of ramen, sushi and chirashi, hearty dishes such as chicken with egg on rice or tonkatsu - yet no detail is neglected. A perfect choice if you're spending a day at the Louvre - you can be in and out in 30 minutes.
