Amazing bento boxes with huge portions. Detailed breakdown below: **Service, 5/5** Super quick service; order using the QR code at your table. There's also way more seating inside than I expected. **Price & portion, 5/5** Huge portions that could probably last some of us 2 meals. Everything is cooked so well and they don't skimp out! **Taste of the food, 5/5** Delicious -- crispy breaded chicken, a variety of tasty and well-seasoned veggies, fluffy rice... what more could you ask for? Makes for a quick, satisfying, and filling meal. The boba is also super solid!

O2 Valley is my favorite bento place of all time. Huge portions for a very fair price. You can also make an account to get points when you make purchases, and redeem them for free food. If you order at the store, they'll give you a receipt with a QR code to scan for your points. When I come I always get the Grilled Chicken Cutlet Bento, No Spicy. You get sooo much grilled chicken. The way they grill it is amazing, very crunchy and complimented by their sauce. The bento also comes with pork bits over rice, a tea egg, and 2 random sides. The sides are also very good and a large variety of what kind of side they're serving for that day. The bento comes with so much food I have enough leftover for another full meal. I also love their Basil Popcorn Chicken. Very crunchy and crispy chicken, and seasoned very well. The fried Basil leaves also taste good, and are more seasoned than other popcorn chicken places I've been to. I've tried some of their milk tea, specifically the Oolong and Jasmine. I just think it's alright, nothing mind blowing.The flavor of the tea could be stronger.

O2 Valley has affordable and filling Taiwanese bento boxes. The bento boxes have everything you want with a soy sauce egg, your choice of meat (I got the braised pork chop), veggies, and rice all for about $16. The portions are so big that I think for some it can be two meals or maybe a meal and a snack. Quick and efficient service and a perfect place for a popcorn chicken snack and boba or a whole meal. Nothing fancy, just good food for a decent price in my opinion.

O2 Valley is doing everything right. Great tasting food with reasonable prices and fast services, there really isn't more to ask for from a local eatery. The patrons can enjoy the inside space as the decor is simple yet promotes a calm space. I really like it here and frequently pay visits when I'm in the South Bay. Pictures showed what we recently ordered bentos, the flavors were very delicious and portions are plenty even for a big guy like myself. The menu are full of delightful choices as well as drinks. Again, it's highly recommended!

O2 Valley is one of those places where I HAVE to give it a 5-star rating. Located across Main Street Cupertino, parking at the restaurant can be tight during peak hours. Inside, you first order at the cashier and then sit at one of the few tables available. Getting to go is also a popular option, and I recommend doing that. For appetizers, I recommend the grilled tofu, as it has a nice peppery flavor and comes with a garlic soy sauce. I also recommend the grilled chicken bites if you want to eat the chicken without the breading. The number one item I get at O2 Valley is the Grilled Chicken Cutlet Bento ($18 after tax), which is a 10/10. You get rice, veggies, an egg, a side dish, and a TON of chicken. I'm always unable to finish the entire bento in one sitting due to the amount of food. The bento also tastes great as the grilled chicken cutlet has a strong grilled flavor, a nice crunchy texture, and a juicy interior. The side dishes and veggies that come with the bento change every week, making every visit different. O2 Valley has other bentos that feature different types of Taiwanese meat dishes, and they are also excellent choices. O2 Valley is a fantastic place to get your fix of Taiwanese food, and I recommend it to anyone who comes to Cupertino!

O2 Valley is a solid Taiwanese bento spot with pretty good value for the money. The in-person dining experience is definitely closer to a fast-food joint with free-for-all seating and by default an exclusively QR code experience (service staff are very brusque, food gets sat down in takeout containers no matter what, etc.). So long as you know that going in, you'll be fine; I was not so prepared so it took me a bit to figure out what was happening. You'll have rotating specials and veggies depending on what's cooking, so what I've gotten in the past will likely vary a bit going forward. Between my brother and I, we had two bentos with the fried chicken cutlet and Taiwanese sauage. Generally fresh and popping, with everything done simple but clean (in terms of flavor). The thing I wasn't too fond of was the chicken texture as it was rather powdery and middle of the road dry. However, otherwise this seems like a great place to be dropping by when I'm in need of a quick and dirty meal that's not too obscenely pricey/unhealthy.

I did an online order for a thai fried chicken bento and a braised pork belly bento. The total was about $36. The online order was ready really quickly, within 10-15 minutes. I really appreciated that the bentos came with various veggie sides. and the portions were huge! Unfortunately the pork belly was too dry for me, but the chicken was great. I'm hoping to try the other bentos, perhaps one of the fried pork cutlet ones or the basil chicken one. The inside had a good amount of seating for dine-in.

Delicious Taiwanese bento boxes and great value - I wish I lived closer to O2 Valley so I could get it more often! We stopped by O2 Valley for a weekend lunch after running a half marathon, so we were all quite hungry. I ordered: + Q1) PaoChung Fresh Milk Tea + K1) Grilled Chicken Cutlet Bento Box My bento box was stacked with the fried chicken cutlet, as well as all of the sides (minced meat on top of the rice, braised tea egg, cooked cabbage and wood ear fungus, braised tofu and peppers). The tea egg was a little dry (clearly braised for a while, from the dark color). Overall, everything was really tasty though. The bento box portion size is also a great deal. I ended up having plenty of leftovers to take home. Everyone else managed to finish their bento boxes and said theirs were good too. The milk tea was refreshing as well.
