I went to Le Petit Rouge for lunch to entertain two visiting colleagues, shortly before Christmas. It is on the first floor, immediately next door to the San Carlo Italian restaurant, and I understand the Le Petit Rouge is owned by the same people. The restaurant is located in the former ballroom of a Grade II listed building.
We were warmly welcomed and seated, and all opted for the French onion soup for starters, which was very nice. As I remember, one of my colleagues asked for a starter from the menu that contained pate de fois gras, but were informed that this was no longer available to to pressure from animal rights groups. I had a lamb tagine for a main course, and my colleague had a whole sea bass, which was spectacular when it appeared on his plate.
The restaurant was quite empty when we were there, but, then, we had book early as one of us had a plane to catch. I should very much like to try an evening meal there, especially when, as per some of the other reviews, there is a live jazz band playing.
