Run by an outfit with broader catering experience, the Wallace Collection's cafe-restaurant is a notch above what you’d expect from a museum. Equally good for a daytime coffee and pastry, an evening drink, or a more substantial French-inspired meal, it’s in the covered, candy-pink-and-white central courtyard. Even potted plastic bay and Japanese maple trees don’t detract from the civilised atmosphere.
Afternoon tea is served daily between 2.30pm and 4.30pm. It's £19 per person, or £27 if you'd like a glass of bubbles with your Coronation chicken sandwiches.
