Trying bubble tea

My daughter and I wanted a new experience so we went to Ealing to try bubble tea. We really had no idea what bubble tea is but had seen a proliferation of places selling it. She had green tea with mango and passion fruit and mine was green tea with coconut milk. The drinks were pleasant but we had mixed feelings about the 'bubbles', which turned out to be chewy tapioca balls about 7 mm in diameter. Anyway, it was interesting and fun.
