I ate there a few days after it opened. First, the atmosphere is great--the restaurant is terrific looking inside (similar to lamberts on the inside, but a bit more "slick"). As for the location, I noted that you don’t feel like you’re anywhere near 6th street while dining there; this was one of my concerns, but turned out to be unfounded.
To start, I had the steak tartare and seafood fritters, both of which were good. The portions are small so you are encouraged to sample multiple items-- personally I like this style, as opposed to ordering one big entree. Then I had the lamb with a side of scalloped potatoes. The lamb had a little too much connective tissue in it, but the potatoes right on the mark. They had a good crudo menu, but I didn't feel like that at the time.
It was the first few days so I naturally wasn't blown away by the food, but I have no doubt they'll be where they want to be quickly.
I jut today read a short blurb in the XLent about this place. This guy had the second version of Jean Luc's on Colorado in downtown A. He was invited to cook a James Beard dinner and I don't think he reopened after that . I always thought his restuarant was quite good. Looking forward to eating his cooking again.
