Set up by Michel and Albert Roux in 1967, the restaurant was the UK's first to be awarded three Michelin stars, although it only holds two now.
While some argue that the dark red and green decor is a little dated and clublike, others think it suits the setting of a serious establishment dedicated to the dining experience. Regardless, legendary maitre d' Silvano Giraldin greets all with an effusively warm welcome.
The food is seriously French and the wine list is not bad either, with prices starting at the just-about-affordable and ascending to the stratospheric.
But if you consider yourself an epicure it makes for riveting reading - 1849 d'Yquem anyone?
While it's certainly not cheap, the £44 set lunch is an absolute bargain and is oddly fitting for a restaurant so determinedly professional in its attitude to client servicing. What makes this restaurant really special though is its sense of occasion and history - it's probably seen more business deals and journalist scoops than its more upstart rivals put together.
