Mmmm, I really love bubble tea. When I lived in Austin, there was this great Taiwenese café chain that made killer bubble tea of about 40 different flavours. I recently quested to find some in London with my boyfriend & we found some at China City, up in Colindale. It's very authentic and totally fresh (we watched the woman slice up and juice the green apples for my SO's drink). I know there's some places in Chinatown that do it, but we've yet to explore them thoroughly. However, I did find a little shop that sells green tea cake, my second ethnic love!!
