O2 Valley

Chinese hot pot and bubble tea spot with a broad selection of broths, fresh ingredients, and customizable dipping sauces.

O2 Valley gives a Taiwanese bento lunch plenty of personality on University Avenue in Palo Alto. Chicken cutlets, basil popcorn chicken, minced pork rice, and Taiwanese sausage form the core of a menu built around individually packed meals. We like the range of preparations, which lets you choose between a crisp fried centerpiece and something braised or finished on the grill. The pork chop selection follows that same pattern, with fried, braised, and grilled versions rather than one standard plate. Grilled eel and pork belly add other substantial choices, while three-cup tofu and king oyster mushroom bentos provide alternatives centered on vegetables. The accompanying vegetable sides can vary, giving each box more than a single main ingredient. O2 Valley's appeal is its focused approach to Taiwanese comfort food, with enough variety to make the bento format worth returning to.
