+1 for UMU. I don't know how I could have forgotton.
For Lebanese in London: Ishbilia

Four mentioned I cannot understand at all:

Fogo de Chão. I know people like them, but I find them pretty mediocre, including the ones in Brazil.

anything Emiril, Ramsay or Waring. I find those formulaic and lacking in quality of service, food but high price.
