About
Generous portions, crispy popcorn chicken, and bento boxes that feel like a meal worth coming back for: that's what we offer at O2 Valley. We're a Taiwanese restaurant in downtown San Mateo, serving bento boxes with pork cutlets and grilled chicken, plus traditional snacks like basil popcorn chicken, Taiwanese sausage, and fried mushrooms.
Our menu changes often, so there's always something new to try, and many guests come back to work through the variety. Our pork chops are sweet, savory, and crisp, with a touch of Taiwanese street-food spice, and our rice is kept separate, chewy, and moist.
We also serve seafood and tempura donburi, alongside bubble tea for a sweet finish. Our downtown location draws guests from across San Mateo and the Peninsula, and our team keeps service quick and efficient, whether you dine in or take out.
