I had been somewhat skeptical of Esszimmer's extensive and expensive prix fixe menus, but was delighted to find that the high praise on Chowhound and Tripadvisor were well deserved. My daughter and I each had the six course Esszimmer menu while my wife had only a couple of courses, but grazed on ours. I was impressed that Esszimmer accomodated her lesser appetite gracefully, as many restaurants insist on all guests taking the same menu; our waitress also encouraged us to substitute dishes on the prix fixe if we so wished. My favorites were the hot smoked wild salmon and the trio of baby pig - chop, belly, and stuffed dumpling; our daughter loved the trio of Char that began the meal - smoked, tartare, and sashimi, all accented with peanut foam. In fact, the chef loves his Asian flavors, but manages not to go over the top - resulting in interesting and not forced fusion cuisine. The service was excellent and the wines accompaniments superb - delicious, unusual, and fairly priced. I particularly loved the 2012 Zierfander Mandelhöh, Standimann, Thermenregion, a varietal which I had never heard of, and the 2011 Grüner Süssenberg from Rainer Wess.
Esszimmer is not inexpensive, but provides excellent value. The portions were perfectly sized - large enough to enable one to savor the delicious subtlety of the chef's cuisine, but by no means overwhelming. It provided a stimulating alternative to the somewhat monotonic Austrian cuisine which we generally enjoyed, but sometimes wearied of during our weeklong stay there.
