This restaurant is in the lobby of the Pur-Navolok Hotel, so it's certainly convenient if you're staying there. We ate there twice: once for lunch and once for dinner. Both times the restaurant was nearly empty, so it was easy to roll in and grab a table.
The food was pretty decent. Not something I'd rave about, but fresh, well-cooked, and well-presented. We had some good caviar, a couple soups (one of which was great, the other so-so), a good salad, and OK mains.
The prices were OK by American standards, but a bit on the high side by local standards. I guess a fair summary here would be that I liked the food just fine, but have had similar fare in a cafe for 1/4 the price.
And I guess I'm not quite sure what one gets for the additional price. The decor (which I don't really care about, truth be told) is, I think, striving to be "sleek modern haute cuisine," but winds up looking a lot like "church wedding reception." The wait staff was good, and the menu in English for a touristo like me, but these are minor things.
A real downside was the wait times involved. We were in no hurry, so it didn't bother us, but wow, our lunch was 2 hours long as each dish was brought out one at a time. It's like the timing is for a super-exclusive high-end restaurant, but it doesn't really *look* like one, so it's a little disconcerting to glance at your watch and realize it's already mid-afternoon.
