For the past eight years, whenever I am in London I have eaten at Denise's restaurant. The food is excellent (and consistently so), the prices are very competitive and the service is always superb and very friendly.The wine list is good and the wine is not over-priced as in some restaurants. Finally the ambiance is wonderfull, and now even better, i can book my table online.
I particularly like the steaks and the chicken chasseur, as well as the wonderful sweets. I can't recommend this french restaurant in the heart of london highly enough!!
