Fabulous Cibo.
26 years ago when my daughter was born, for the for 6 months we did not go out to dinner. I had saved up enough for a blow out, arranged for the M-i-L to babysit and my wife gave me a choice of 2 restaurants to pick from. Although half way across London I chose the Italian - Cibo. We were rewarded with the sort of meal that you could only have in Italy.
From then on Cibo became our place, the food and hospitality has over the last 26 years always been consistantly marvelous, and now that we live outside of London it has become my family's goto place. When I asked my rather sophisticated daughter where would she like to celebrate her birthday - she answered Cibo.
I strongly recommend you to try it, and you will know exactly what I mean.
