Please, no offense meant, but I tried the Giraffe near the London Eye in central London and found it horrific - even the burgers. But I thought maybe it was just that day/location so I tried it again about a year later in Heathrow. Even worse. I'm not blaming the Giraffe. Kind of think of it, I've rarely found good food in the UK IMHO. Although one of the best meals I can recall WAS in London, it was the rare occasion and it was at L'Atalier de Joel Robuchon in Covent Garden. Fantastic lunch. On par with the same restaurant in Paris and Tokyo in fact. Now, if one considers that place a "chain", it is one amazing "chain" restaurant!
