Huge portions and yummy Taiwanese flavors. We topped off our bentos with drinks and the passion fruit yogurt smoothie under the fresh milk category is DELICIOUS. Like a tart frozen yogurt with a hint of passion fruit. Less sweet was perfect.

⭐️⭐️⭐️⭐️⭐️
Absolutely love this place!😍
O2 Valley serves some of the best Taiwanese lunch boxes around. The food is super tasty, portions are huge, and the prices are very reasonable.
It doesn’t matter who you are — if you love good food, you need to give this place a try. Definitely one of my go-to spots when I’m craving something hearty and satisfying!

Braised pork rice was lacking in flavor and overpoweringly sweet.

Somewhat chaotic service process for dine in.

The door doesn’t close automatically so people often leave it open, letting drafts of cold air come in.

The whole place runs on single use disposable everything…
