Claridge's has an actual tea connoisseur on board for their afternoon tea menu, so you know they take it seriously. It's worth noting this review, which adds that "the sandwiches arrive on that distinctive stripy china, and they keep on arriving until you stop asking for more."
Sip your tea and nibble your sandwiches in the sumptuous pink velvet booths of this Michelin-starred restaurant. If you're on a budget, their cream tea (fruit scones with jam, clotted cream, and a choice of teas) comes in at a very reasonable £10 per person.
Sure, they do a marvellous traditional afternoon tea, but what makes Bake-a-boo really stand out is their "sensitive" menus. There is a gluten- and dairy-free menu, a dairy-and-egg free menu, and a sugar-free menu. Wonderful!
The first Maids of Honour shop was founded in the 18th century, so you can be sure that these guys know their scones. There are plenty of options to choose from, and all menus apart from the champagne cream tea come in at under £15.
