This tiny shop was the first ever Twinings shop, and is now something of a tourist trap, but it’s actually a good place to buy some tea. Interesting history aside, they have more types of bagged tea than you can shake a stick at, and a good selection of loose leaf teas, many of which you can try. Staff are knowledgeable and friendly, and it’s a really fun place to go. I bought a wonderful Keemun Mao Feng which was pricey but worth it. They stock all types of tea.
