This was clearly an outstanding experience to visit Andy Meyer's restaurant, probably the best of entire Austria.
I would not even like to compare it to anything else in the area, as it offers a state of the art combination of modern fusion cuisine with elements of molecular kitchen, so no hamburgers or schnitzels (however, to be fair - restaurant of that level can make anything on your demand - people at the next table have ordered pizza for the kids, and it looked great as well). Every course served was state of the art, besides one dish simply surprised us - we were given a special sound headset to accompany one of our meals - what a great idea to combine the food and the sound of nature! Unbelievable experience.
Price - yes, it is high. Very high. But comparable to other Michelin-starred restaurants, it was not a surprise for us and actually were expected to be that way. We have selected 4-course degustation menu, which was about 130 Eur per person, +4 course wine degustation for about 59 Eur per person + some other extras like aperitif champagne.
Portion sizes seems to be small at the first glance, like any restaurant of that level, but in reality it was actually even difficult to finish everything (with all the compliments from the chef), as you enjoy your food slowly over the time with explosion of taste senses with every single piece you take, you need no more! 3 course degustation menu I would say would be enough to enjoy, otherwise it can be even too much.
Wine match offered by restaurant was OUTSTANDING! It will give you an opportunity to enjoy your meal the most, especially you prefer to taste a variety of dishes, combined with the best selection of top local wines. Well done!
Few words on the design of the restaurant: there were some reviews below where people didn't really like the interior, calling it "plastic and superficial" - well, in my opinion - restaurant is PERFECTLY set, allowing a lot of personal space and not to interfere much with other visitors, large tables even for a small company which I find very convenient, VERY tastefully decorated area. Yes, it resembles traditional feel of pine wall panels (as ultimately this IS a castle in the mountains which is traditionally built), but elements of decor so much belong there - combination of old and modern made it a very enjoyable surrounding, very light and bright, great deal of details were put into design. So in my opinion, this place is by far better of some other Michelin restaurants I have had a pleasure to visit.
A tip at the end: do not go for desert within your degustation menu (just go for 3 starters/main courses) as ultimately desert plate is huge and was difficult for us to finish it, besides there is a complimentary sweets offered at the end anyway to your coffee.
Would love to return there one day for new experience.
