Restaurant name

I have never been here, but a friend I used to know told me about a nice restaurant in Houston years ago. I believe the restaurant requires a reservation, and it is a hidden restaurant almost, where they lead you through a restaurant open to the street, through the kitchen and behind the wine cellar there is another restaurant.

I have been trying to figure out the name so I could go to it for months but am unable to. Does anyone have any ideas what it might be?
