Last week I tried a brand new sushi restaurant, Origami, in Esch Belval. The waiter informed us that they had opened only two weeks before. From his "chicken maki" suggestion, I gathered that he hadn't fully familiarized himself with Japanese food yet. He was very friendly and apologetic though, so we let his gaffes (there were several) pass as funny incidents.
As you can see from the photo, my sushi combo was beautifully served. The food also passed my does-it-taste-authentic test.
The place is fairly large and there were surprisingly many people given the fact that it's a new restaurant and that the summer holidays were still on. I will certainly return and give their sushi train a go next time.
