Onyx Restaurant

Dining at ONYX Restaurant Vienna, perched on the 6th floor at Stephansplatz, is a visual and culinary dialogue with the city itself. The uninterrupted view of St. Stephen’s Cathedral feels almost cinematic Vienna unfolding beneath you while the energy inside hums with purpose. The space strikes a rare balance: vibrant yet cozy, elevated without pretense. The fiery robata grill and sushi counter create an interactive rhythm that mirrors the room’s pulse. Add the refined lounge beats, and the atmosphere becomes immersive measured, confident, and effortlessly cool. The menu delivered with precision and personality. The Avocado Asparagus Maki was clean and refreshing, lifted beautifully by yuzu mayo and shichimi pepper. Organic Chicken & Prawn Gyozas were delicately crisp, deeply savory. The Nigiri selection hamachi, ebi, eel, & avocado was balanced and well executed, while the Sliced Yellowtail Carpaccio stood out with its elegant citrus truffle dressing. From the robata, the Sweet Corn with shiso and shichimi surprised with depth and warmth, and the Spicy Fillet of Beef was bold, tender, and unapologetically flavorful. The Lettuce Avocado Wasabi Salad, finished with carrot ginger dressing and pumpkin seed oil, offered a refreshing counterpoint clean, crisp, and thoughtful. ONYX is not just about dining; it’s about tempo, texture, and perspective a place where Vienna’s historic soul meets contemporary confidence, both on the plate and beyond the glass.

My wife and I decided to visit for a quick drink to soak in the view, and we are so glad we did! The hostess Julia was so professional and kind and made our experience amazing. We were sat at the bar and we had a front row view of the expert chefs crafting amazing sushi. The precision, presentation and harmony in the preparation were perfection! Everything we ate was amazing and so fresh! Would highly recommend this place to everyone and once again thanks to Julia and her amazing team.

I need everyone who is looking for a review to take a look at this. This restaurant genuinely surprised me and having such a good experience at a restaurant these days feels impossible. Even for my 18th birthday i decided to travel to Milan,Italy and dine at a very "good" restaurant. Every expensive restaurant treats their customers superficially but this was not the case. Me and my friend really wanted a window seat and we were willing to wait for them to free a table in that area and they did. The waiters were extremely nice and very communicative. Regarding the food: I always tend to go to places that offer me a bigger food portion but i was pleasently surprised when it came to this culinary experience. The portions were small but they definitely satisfied my taste buds! I am a cook myself and I can really say that the taste of everything was so balanced and just perfect. For desert , we had a chocolate mousse. The taste was incredibly delicate. It takes good experience in the culinary field to appeciate the fine taste of everything Onyx has to offer. Regarding the hospitality: We met a romanian waiter that was so communicative and genuinely had a good time interracting with people. I hate it when the staff of a restaurant acts like a robot but this was not the case. We had a good conversation with the staff of the restaurant and that genuinely made our night so memorable. In conclusion I would absolutely recommend Onyx for any special occasion.

Wow, we had an amazing night here. Service from the moment we got off the elevator was spot on. Everyone was so friendly and professional. The service - amazing. The food - fabulous. The atmosphere - unmatched. Views - incredible. If anyone has anything bad to say about this place that's on them. Our drinks were never empty. The food was incredible. So grateful for such an incredible evening.

I have to say, I was amazed by this place for so many reasons. Before going, I had seen a lot of negative reviews online, people complaining about the price, the service, or being disappointed overall. I wasn’t sure if I wanted to go, but we decided to give it a try for our wedding anniversary, and I’m so glad we did. We had a window table, and the view was absolutely stunning, watching the cathedral across the street was the perfect backdrop. The food was 10/10, seriously some of the best I’ve ever had. The service was amazing—super helpful, attentive, and knowledgeable about everything they serve. I honestly have nothing bad to say about this place. What I learned from this trip is not to pay too much attention to bad reviews. I don’t know what people expect, but my experience was incredible. For someone who travels a lot, this is definitely a restaurant I highly recommend and one I would happily return to if I go back to Vienna. Also it’s super easy to get a taxi around this area. By the way, I don’t have pictures of the food or us because we decided to just enjoy the occasion and the view, and I’m so glad we did.

Although we went there with a reservation, we couldn’t get a near window table because we reserved the same day. But anyway, the view of this restaurant is fantastic and you can’t miss it. The food was high quality. I tried almost every sushi and I liked the spicy one. The salad was also creative and tasty. Shrimps and dumplings were also perfectly cooked. The staff were nice and helpful.

I would go here again and again!! Totally recommend. The view was beautiful, the service was on top and the girls that served us were the best. The sushi was freshly made and super delicious. You could even see them making it, so everything was transparent. A little expensive but for the place and quality i think its okay.

This was a delicious meal, great atmosphere and stunning view. I would wholeheartedly recommend the popcorn shrimp (we ended up ordering a second) and my drink (the golden raspberry) was an event of its own. We didn’t feel rushed through our meal and when we asked our server to take a photo he recommended we go outside for a better view. Would absolutely return!

Great place. Quality drinks and a view of the church up high that cannot be beat! Note: take the elevator near Zara up to the bar and enjoy your evening! It can get crowded on weekends so you might want to get their early

I travel to Vienna every year, at least once, and I always go to Onyx-Bar for the beautiful service, the beautiful view, the fine Hendricks on the rocks, and the perfect club sandwiches. If you are not getting the most professional service here, you are not tipping properly. It's a beautiful place, in the middle of the first district, with a great view and great drinks, so you need to tip well to get the service you expect. I have no problem giving the waiter 20 Euro for my first drink. All goes well. I LOVE this place.

This is another great bar to check out while in Vienna. It's is upscale however it's in a hotel so families sometimes bring children. We did not have to wait long for a table. It has a nice view or the central area of Vienna and the drinks were good. I would come here again to have a drink.

The view is okay, now amazing at all. The place is really pricey, especially considering that the drinks on the menu are pretty standard and not amazing at all.

Much too overpriced for the small drinks. You pay for the view, which is beautiful, but the food and drinks are not worth it. However, the service is exceptional and very classy.
