3 Best Restaurants in St. James's, London

A sophisticated crowd enjoys the sumptuous and elegant decor at this classic brasserie at the back of the royal grocer, Fortnum & Mason. An old-school trolley arrives 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. It's open all day, with an unusually long five-hour window for lunch bookings—perfect if you want to take a break from shopping nearby.

A glitzy procession of famous faces, media moguls, and hedge-funders comes for the spectacle, swish service, and soaring elegance at this bustling Viennese-style grand café on Piccadilly. Located in a former Wolseley Motors luxury-car showroom, this brasserie begins its long decadent days with breakfast at 7 am (8 am on weekends) and serves Dual Monarchy delights until 11 pm (10 pm on Sunday). Don't be shy about popping by (they welcome walk-ins) for dishes like kedgeree, steak tartare, chicken soup with dumplings, or Wiener schnitzel. For dessert, go for an éclair, and don't forget to return to savor the classy afternoon tea.

Tucked away down a pedestrianized back street, this casual French bistro is a favorite haunt for politicians based in and around the nearby Palace of Westminster. Open all day, one can only imagine the political intrigues being discussed over Gallic classics such as coq au vin or snails in garlic butter, all washed down with wines from the surprisingly extensive list.
