This place is suggested to serve the best roast dinner in all of London, and I'm inclined to agree. Everything about the restaurant is traditional, from the seating booths, to the serving plates. Originally a chess club, this classically British restaurant has had many notable visitors in history, from Charles Dickens to Van Gough.
If you have time for a drink beforehand, go to the Knight's Bar which has an art-deco style and is really beautiful.
Location: Clue is in the name.. On the Strand!
Cost: £35-£70 depending on the number of courses and the wine you order
