I'm new to FT.. I've been browsing the forum for several days now..and this is my first post. I hope I can help.
I fly to Austin pretty often, and each time I always stopped at a bubbletea place called Coco's Cafe. They have good selection of flavors.
And in Houston, there are probably more than 20 places that sell this type of drink. Go to the new Chinatown ( Bellaire Blvd ), and you will find plenty of places. The one I usually go to is located in the Hongkong City Mall.
I've also tried bubbleteas in NYC, Pittsburgh, Chicago, Seattle, LV, LA, SF, and back home in Indonesia.
They're all good! ^
Btw it's also called "Pearl milk tea", "tapioca ball drink", "boba drink"
Here's some other locations that I found on the net:
