A brief update to my previous review. I have eaten there a few times recently, and I have been very pleased in almost every respect.
The food can be spectacular - among the appetizers I still like their tartare very much and the yellowtail, of Japanese inspiration, was delicious - the apple mixed with the raw (?) fish was surprisingly successful. Among the entrees, the duck is invariably good, but I particularly enjoyed the sturgeon - first time I had this white fish, firm flesh, but less so than tuna or shark, and tender. The chocolate dessert with sesame and banana is fantastic.
A few things could still be improved - it can be a bit fresh in the restaurant, and there is still no expresso. The coffee remains mediocre (see other reviews).
I prefer eating in the main room downstairs than upstairs.
