At the back of Fortnum & Mason is the old-fashioned Fountain, as frumpy and popular as a boarding-school matron, serving delicious light meals and ice-cream sodas. During the day go for Welsh rarebit or Fortnum's steak-and-ale pie; in the evening, a no-frills steak is a typical option. It's just the place for afternoon tea after the Royal Academy or Bond Street shopping, and for pretheater meals. Tube: Green Park.
