O2 Valley

O2 Valley offers authentic Taiwanese cuisine specializing in generous portioned bento boxes and popular snacks like popcorn chicken and fried chicken cutlets. The food is consistently praised for its fresh ingredients, flavorful seasoning, and excellent value. While the milk teas and boba drinks are decent and complement the meals well, the primary focus remains on food rather than beverages. The service is friendly and efficient, with a casual atmosphere aimed at both takeout and dine-in customers.

Most Popular Items

Popcorn Chicken Bento
"Got the popcorn chicken bento and was surprised to find a quarter of the bento be popcorn chicken. They didn't skimp out on the meat! Really complete meal as well, with veggies, protein and rice."
Chicken Cutlet Bento
"I ordered the R2 Chicken Cutlet Bento, and the chicken was crispy and not dry. Wish it had just a bit more seasoning on it. The side dishes/vegetables were cooked excellently — tasted as expected for stir-fried vegetables, not bland or oily — and the minced meat topping on the rice added savory notes to the rice."
Grilled Chicken Bento
"Good portion for value, my favorite is always the grilled chicken bento. Great place for both quick takeout and dining in."
