Koio Tea Shoppe (diamond - Diamond Bar

This is a great tea and boba shop to visit! I tried the brown sugar boba milk tea and it was delicious. I highly recommend this place for anyone looking for some boba drinks.

I love the taro boba at this restaurant. They use real taro, not artificial with purple coloring. The taro flavor isn't too strong, but the texture of the taro is great. The boba is very chewy with a hint of sweetness. The regular sweet drink is also delicious!

The staff was friendly, the location was clean. The drinks were delicious, not too sugary. Will definitely return. Highly recommended!

My favorite is the sweet potato milk tea! very creamy and they can taste the purple yam.

Ummmmm, they don't wear masks. The drink was tasty tho but they don't wear masks.
