We serve the best bubble tea around the Bay

Welcome to  Green Bubble Cafe

Mr. Green Bubble was founded in 2010. this was a venture started by Can, Joanne and Sandy, we are always the bubble tea lovers and wanted to bring the real taste of boba drinks from our hometown Taiwan. We had just graduated from SFSU and worked in different fields as computer sciences and fashion merchandisers, but we wanted to make our dreams real and created the authentic boba tea shop. We are sharing our passion for boba drinks by bringing them to America and established our first shop on Piedmont Avenue in Oakland.
