I went a while back. Only had one meal, though. I found the food carefully prepared, but overly simple and lacking layers of flavor. There just wasn't much depth, I thought. Haven't been back partially because my wife thought it was a pretty bad value. Those cabbage rolls, eg, were small with very little filling, mostly cabbage. It was too much in the Navarre/Luce vein for me, except with better presentation and consistency of execution (and service).
I don't disagree with most of your comments. The price point was a bit high for the portion size, yes. We shared two smaller plates and two larger plates, and I definitely could've eaten more. And the flavors were simple, but I enjoyed that the dishes were straightforward and not trying to be more. Whether they were overly simple may depend on the person. Regardless, I really enjoyed the meal, though b/c of the value issue you mention, I'm not likely to go there often.
When I say "simple", I don't mean that I need a bunch of things going on. It could be a simple piece of meat with a sauce and nothing more. I mean that the flavors were flat and one-dimensional. For instance, I also had the leeks braised with matsutakes. I felt it was flat. It was really just leeks infused with matsutake flavor with some slices of the mushroom on top. Boiled mushrooms with boiled leeks. And no attempt to balance the woodiness at all. It wasn't bad. But I need more if I'm going to go out to eat, especially if it means dropping some real change.
Been reluctant to say anything after one meal, but I know that I'm not the only person here who isn't a fan of extreme simplicity.
