Not the best tea in Oakland.
While it does have the option of being highly personalized to the consumer it lacks in quality. There are better bubble teas (and cheaper) in Oakland (like Chick'n Bubbly).
They also offer a limited selection of classic bubble tea flavors! Even Asian restaurants in Pittsburgh offer more diverse flavors than Fuku Tea. If a restaurant specializes in tea, I would hope they they put more effort in creating a myriad of options that you couldn't get elsewhere. I could go to any restaurant that serves bubble tea and ask them to not add sugar.
