We went to this restaurant due to great Google recommendations. We came very late in the evening without a booking. It appeared that this evening was some special day for Icelandic people, and the restaurant was full. However, they managed to give us a table...and very quick service. We ordered various sushi rolls and sushi pizza. Actually we were very sceptic because sushi pizza sounded like some cheap thing for kids. It was very good and not like a regular pizza :) the sushi quality is high here, based on fresh and good quality fish. The sushi style is Nordic style and not Japanese. However, it tastes good! Service was excellent, and fair wine prices. A lot of reviews comment that this place is expensive. It is not. We paid around 140 Euro for a good bottle of riesling, 2 glass of riesling plus 8 dishes. Anything like this would be far more expensive in the other Nordic countries. Good quality fish is never cheap. If you like fish and enjoy quality food, you will probably enjoy this restaurant.More

Lunch buffet offers an extensive choice of sushi, cooked meat, fish, vegetables, salad and noodles, water and coffee included. Food quality was excellent. Dishes on the buffer table replenished frequently. About £20 per person. Good value for money.

We went two couples. We ordered fish. The guantity of the fish was exactly like two small matchboxes. Can't feed a human. The taste is unknown because the strong sauce. The vegetables was good. The prices for each plate is around 37 USD. After the...restaurant I went home and ate a toast with turkey and tomato. Delicious!!!More

Dining is expensive anywhere in Iceland, so the service level is paramount to a fine dining restaurant. It was raining/snowing really hard that night and we lived in the hotel across the street. Perfect place to get something to eat. Initially trying JP food in...Iceland was not our first choice, but Rub 23 did not disappoint us. Everything is nicely cooked and presented, and the service was very good. As JP food lovers, we are surprised that we could find this kind of quality JP food here, not authentic but full of Icelandic character. Make sure you make reservations.More

If you're looking for something different, you need to try Rub 23's sushi pizza! Made with fresh arctic char, the dish is light and flavourful. The decor of the restaurant is quite nice and the staff were professional. I tried their wasabi cocktail sour and...it was also delicious. I highly recommend this restaurant!More

The two of us had the special triple deal. Did not skimp on any quantities , maybe too much . However the quality of quiisine was excellent . Apart from maybe a little to much dressing on the lamb, We could not fault the overall.... Up there with our best on tour mealsMore

While touring the wonderful country of Iceland, we had the good fortune of being treated to a fine, fine dinner at Rub23. Dining almost anywhere in Iceland is expensive so you can count on it here too. However, the food here was as good as...I have had anywhere. We would definitely return.More
