The place looks really nondescript from the outside, but boy it's good. They have various happy hours throughout the day and the sushi is freshly made in front of you. During evening rush hour it is around 16€ pp. and they have a wide variety including miso soup and tea as much as you want. The staff is extremely nice and welcoming. At the front desk is a Japanese cook welcoming you and you can watch him as well preparing the food. The sushi is constantly made fresh no piece is lying around longer than 10 min. It seems to be an insider tip. If you like sushi you should definitely pay samurai sushi a visit.
