There are many places in Chinatown. My favorite is KC's Pastries, where the red bean bubble tea is made with real red beans, not flavor powder. I haven't tried the fruit ones but they say 'fresh watermelon, fresh mango' so I'm hoping they are made with fresh fruit. Great Tea International on Sansom around 16th does a great matcha green tea bubble latte. There's another new tea place, also on Sansom around 16th that I'm sure does bubble tea. Thank you.
