Rococo chocolates was founded way back in 1983, quite a long time before foodie businesses became mainstream, but in areas like Belgravia, Chelsea and Knightsbridge where Rococo functions, this kind of specialist store is emblematic of the area and the people who shop there. As the name suggests, these are deliciously decadent chocolates, think gold leaf, fine ingredients and velvety textures. They go perfectly with the area itself, Knightsbridge is all about luxury and fine living but it doesn't forget to support fair trade chocolate and cocoa farmers too. There are all sorts of interesting flavours here, but one of the new arrivals is rosemary and seasalt suspended in an artisan milk chocolate. There is also a summer pudding, white chocolate with mixed berries, and salty caramel balls disguised as seagull eggs. Makes the perfect present or special treat for oneself.
