I couldnt agree more with overall review of Riva especially the comment about service. I have eaten at Riva a number of times now and sadly the head waiter has always given me the opportunity to not to want to go back. i love the food and even the slightly scruffy appearance but the head waiter…he has the ability to look down his nose at you with some skill. Having eaten there last night and held my tongue due to the amount of shell in crab raviolu i couldnt help but politely point out the high number of bones found in the Sea Bream (de boning one is not easy i am told) but his response was unbelievable he turned very agressive and almost informed me i was an idiot (perhaps I am). Sadly his continual ability to be fantastically rude means i might not be able to go back, as i love the food…maybe one last chance
