While not Viennese, we live in Vienna and we're adventurous eaters. And, let's just say that (fried) Schnitzel and Tafelspitz (boiled beef) has gotten old. I had read the hype on this restaurant and listened to the accolades from friends, and finally got around to having lunch here with my husband and son.
The outdoor setting is wonderful; a beautiful shaded area dappled with sun just off the busy section of Praterstraße. We sat for an early weekday lunch (11:30), and within minutes every table was filled, with people hovering about waiting for an opening. Waitstaff were friendly (ours was a bit forgetful, though).
We started with Edamame, nicely crisp and tossed with a perfect fusion combination of sea salt and horseradish. Our lunches came with either miso soup or salad. The guys declared the miso soup quite good; I enjoyed my mixed green salad with a light sesame dressing--no leaves were drowning in my bowl. I ordered the "Spicy Salmon" sushi with avocado, innovative in that the salmon was finely diced rather than as a whole piece, but more "Austrian spicy" (that is, not at all spicy) than having a true spicy tone. Still, my lunch was good. Our son ordered the Ebi Katsu Don of crispy shrimp atop a daikon and rice bowl that was of good portion and flavor. My husband ordered the Tori Katsu Don, a similar bowl with chicken that was horribly over salted. He reported that when back in the office that afternoon he felt a bit upset from the salt overload.
Will I dine here again? If out with friends who suggest it, then yes, for the sake of consensus. Will I suggest the restaurant? No. It's popular and trendy, but just good-ish, not great, and definitely not worth hovering about waiting for a table.
