A sophisticated crowd enjoys the clubhouse vibe at this classic brasserie at the back of the royal grocer, Fortnum & Mason. An old-school trolley trundles up table-side to serve Siberian Sturgeon caviar with scrambled eggs, baked new potatoes, and blinis, while creamy beef Stroganoff and whole duck with elderberry sauce get the full table-side-flambé treatment. Truffles that are shaved at the table are another specialty. The popular Welsh rarebit toasty has a punchy mustard kick, while nostalgic desserts include a fleet of alcoholic ice-cream floats.
