We had previously read about Taiwanese bubble tea on the internet and so when we came across Bubblebase in Cardiff we had to give it a try. No one can tell you exactly what bubble tea is, as, like the Matrix, you must experience it for yourself.... save to say our passion fruit with mango popping bubbles was gorgeous! The staff were super friendly and extremely informative, taking time to explain the numerous options available in depth. It's obvious they love their bubble tea, and so do we! Excellent!
