Unkai Bar & Sushi - Kärntner Ring 9

Very High class and great quality. Worth the price. The staff is very polite and super helpful and friendly. Highly recommended by us !!!

Had a craving for sushi, so called to order takeaway from Unkai. The salmon sashimi was very fresh and good value (9-10 slices at 14 EUR), but give the piece-by-piece sushi a miss (7 EUR for each piece of Hamachi sushi ?!)

Ground floor bar Good location, reasonable prices, nice outdoor seating and a good service. Food, quite disappointing - we had some maki and nigiri; first time that maki was not good, it is a very simple dish but I suppose when it’s not great you notice it. The soy sauce tasted and looked diluted; maybe wasn’t but it was very mild and that negatively affected the taste of the food.

We went to Unkai for a sushi brunch (~30€) on a Sunday. We were very surprised about the quality of the fish and various nigiri sushi choices. The sushi brunch comes with Miso soup and salad. Staff is very professional and kind.

It's sort of the places I've searched in Europe for long time - one where you can taste really good Maki. Their prices are little bit higher than you expect it to be, but the atmosphere, service and food quality is really worth it - we have tasted Miso soup and two sets of Maki - Casual and California, first one was just okay with few really nice rolls but that's it, but second one was just amazing - looked great and tasted wonderful as well, we drank jasmine tea - good, however pricey. To conclude - great atmosphere and service, delicious food, but better to use photos to get best they can.

Very poorly run restaurant. My server wasn't well trained, and it was very distracting to have him around. Drinks weren't getting refilled. Food isn't anything unique or particularly good tasting - anyone could easily make everything at home at literally 10% cost of what they charge. Teppanyaki service is extremely slow (took about 3 hours), and for what they charge, I expected the chef to cook everything from appetizer to dessert infront of me on the grill. The reality is, maybe only 2 or 3 dishes were cooked on the grill infront of me out of a full Unkai course meal. By the end of the service, I couldn't wait to get out of my seat. There are hundreds of better ways you could spend your money. Horrible, boring, mediocre, undeserving. I regret this visit, and I will never be back again.

We went for the sushi brunch (12:00-2:30PM) for 36€ per person. There were various freshly made nigiri, maki etc. Perfect service and explanation of the buffet. Money well spent. We'll be back.

The restaurant is located on the seventh floor of the Grand Hotel Wien. His name is UNKAI and it can be translated as "sea of clouds"! Un unforgettable experience : we tasted most sushi compositions and finest natural aromas. Fantastic !!! Very friendly and professional staff who explained all the orders to us. All Covid 19 rules respected.
