I have eaten at Cantinetta quite a few times and always had brilliant food ( the new chef turned up 3 months ago and I think his food is fantastic.)
The Spaghetti with crab is gorgeous and the fresh swordfish is the best I've ever eaten.
The place seems to attract celebrity as I've seen the LeBons in there and Bob Geldof, Andrew Marr, even Nick Clegg. The service was as I like it ! Attentive and caring for my dietary requirements.
I have taken friends with me and they have always gone back with their friends. I have eaten at many restaurants but always enjoy Cantinetta's food quality / price.
