One sip every body knows the rules. Had the avocodo mango smoothie with honey boba half sweet. Probably one of the top Avocodo smoothies I had. Boba is soft and chewy which I like. Fire 🔥

Great boba option to turn to here in Hayward that offers oat and soy milk as non-dairy milk options - a win in my book.

The shop is large with many drink options and snacks to choose from. You order from the kiosk in front but can ask the staff if you have any questions.

I ordered a Jasmine Milk Tea with Oat Milk and it was perfectly made. Highly recommend a lower sugar level since it's sweet as it is. They also did a great matcha latte...

We discovered this place while house hunting in Hayward. There are parking spaces nearby. Would definitely recommend B5 Strawberry Blizzard With Sago. It's so delicious. We drive from San Francisco just to get drinks from this place.
