Bubbleology cafés, the home of quirky drink Bubble Tea, are celebrating their first birthday with a free drink for all London customers this Sunday (22 April).

Popular in south-east Asia, bubble tea is a fruit-infused tea-based soft drink that has caramel-flavoured pearls of tapioca at the bottom. Now Bubbleology are celebrating a year of bringing the quirky drink to London with a cheeky giveaway.
