Very delicious bubble tea shop on Forbes in Oakland. They have all sorts of great flavors, and will take the time to answer questions if you are unfamiliar with the popular drink. There are also snacks and candy from Asia that are not popular in America for sale as well.
I went with a passionfruit flavored tea with tapioca boba. I'm usually a fan of black tea with milk but I wanted to venture outside of my comfort zone, and I'm glad to report it was great! The only downfall that would keep me going back is the price--a large tea is upwards of $5, and that can be an expensive habit quickly.
