Mr. Green Bubble in Union City is always my go-to spot for boba! I love getting their popcorn chicken and garlic fries. You can choose your spice level from 0–5, and level 3 is perfect for me—not too spicy, but just enough to feel the kick. The garlic fries are amazing because they load them up with garlic. I do recommend grabbing a fork since the garlic doesn’t stick very well to the fries and can fall off if you use the sticks they provide.

We love it the service is great! The snacks and drinks are even better!! Today my son (who is very picky) tried the tofu and he loved it! For our drinks we got the mango peach slush with some popping bobba and a honeydew milk tea with oat milk and they were so refreshing and yummy, I am definitely getting the honeydew one again! Thank you Mr. Green bubble for having some really delicious snacks. I look forward to going back again soon!!

Mr. Green Bubble in Union City is my favorite spot for boba! Their drinks are consistently delicious, with a great variety of flavors and toppings. I especially love their fruit teas and milk teas – always fresh and perfectly sweetened. The staff is friendly and quick, even when it's busy. Highly recommend for a refreshing treat!
