"A pleasantly light and modern restaurant where you can eat either at authentic teppanyaki grill tables or more conventionally. You will also find the Unkai sushi bar on the ground floor serving a sushi brunch on Saturdays, Sundays and public holidays." - Michelin Inspector

A lovely rooftop restaurant with an elegant design. Very nicely presented authentic Japanese food, which was delicious. The service is also very attentive and friendly. We came for a birthday dinner and had a great five course meal. They also have a good vegetarian selection. Dogs are welcome at the restaurant, and our dog was kindly offered a bowl of water too. I recommend this fine restaurant for special occasions.

Dinner | 1 person | 67€ tldr: good food, high prices ___________________________________________ I ordered some Oolong tea, the 12 mixed Nigiri (substituting the Tuna with Ama Ebi due to preference) as well as 1 Scallop and 1 Eel Nigiri each. Additionally I got served a bit of pickled/marinated mackerel as a free starter. ___________________________________________ Pros: The mixed set, which goes for 42€, had a nice bit of variety. Fish seemed high quality, fresh, and tasted great. Ratio of fish to rice seemed just right. Rice perfectly seasoned. The single sushi are quite expensive but were, alongside the Ama Ebi, the stars of the night. Both scallop and eel (7€ and 10€ respectively) were exceptional. The service staff was friendly and polite as well as knowledgeable about the dishes they served. ___________________________________________ Cons: Sadly the salmon roe Nigiri was kind of a let down as it did not at all feel balanced in flavour (not enough rice) and had several hard pieces of rice in it. The octopus Nigiri, while great in taste, was rather chewy and hard to eat. Portions were more on the small side which was to be expected. Ginger and wasabi seemed standard (not sure if real wasabi or cheap paste which would be a shame with prices like these). Waiting time to be noticed when wanting to pay were a bit long but this could have been due to the table I was seated at being not that easily visible. ___________________________________________ Overall I had a pleasant experience (if you ignore the few hard pieces of rice and the chewy octopus) and was very happy with the food. I did have a coupon (which made dinner a lot more affordable), however it was not considered in this review. Would I go again? I don't know. As amazing as the food might have been, 67€ (without tip) is still quite a lot of money. The little slip ups might not seem too problematic but in this price range and when talking about a Michelin Star restaurant it shouldn't happen. Maybe revisiting for special occasions and probably with another coupon but definitely not on a daily basis (at least for now). ___________________________________________ S Tier: Scallop, Eel A Tier: Ama Ebi, Yellow Tail B Tier: Squid, Salmon, Sea Bream, Sea Bass C Tier: Ebi D Tier: Mackerel, Oktopus E Tier: Salmon Roe

This Hotel has the best Japaneese Cuisine Restaurant in town. Very elegant syle, clean and amazing staff. You will not know what you have missed if you don’t visit this place. Restaurant is on the 7th floor of the Grand Hotel in Vienna. Booking in advanced is recommended.

Went here for AfterWorx all-you-can-eat sushi. The fish is high quality and there are plenty of choices. The sushi chef prepared the sushi fresh (12 choices) and 6 choices maki are available on a plate. All delicious and worth its price considering the quality and freshness.

I think it's a beautiful place to visit, but to be honest, I wasn't impressed. There's nothing more to say.

We had some very good sushi at a very reasonable price. The fish is of good quality, with a good choice of different fish varieties. The rice is seasoned perfectly, and the proportion of rice to fish is excellent. All in all, it was superbly executed sushi. As we were seated at the sushi bar section, not in the main restaurant, the seating area is very cramped, and the sushi bar is not properly designed, as it doesn't allow for normal seating, rather than some very unusual pose with legs on the side. I would definitely recommend the restaurant; however, I would suggest asking to be seated in the main restaurant area and not the sushi bar.

A nice restaurant, small and friendly. Food was tasty but portions were on the small side. It is pricey but within reason. Sweet were not that tasty though
