    Ordered through qr code and everything came out super fast! All the fried foods were done perfectly. Extra crispy on the outside but still moist on the inside. They have a good variety of bento boxes/ combos and a la carte. Price was pretty good for the portions! We dined in and luckily snagged the last table but take out would be a great option too!

    This place's food reminds me of the Taiwanese bento boxes I grew up eating! Cannot recommend O2 Valley enough - delicious food, huge portions, and a variety of options. I visited on a Saturday afternoon, and it was quite busy. After 1pm, however, the crowd started to clear. The interior is minimally decorated, and there's a fair amount of seating. The bento boxes were the star of the show! I can't get over how much food was in a single bento box - one bento could easily last you two meals. The popcorn chicken was fried to perfection and covered in fragrant spices. The accompanying sides were also delicious! I really enjoyed the grilled chicken. It honestly seemed more fried than grilled, but it was tasty nonetheless. The grilled chicken portion was somehow even bigger than that of the popcorn chicken. There were two huge pieces of grilled chicken, all covered in a sweet and tangy marinade. The golden kimchi paired well with the bentos and cut through the richness of the meat. I've heard great things about the drinks here as well but didn't get a chance to try. Just another reason to visit again! If you're looking for comfort Taiwanese food, O2 Valley is the perfect place for you!

    Chicken Cutlet Bento
    Felicia C.

    O2 is probably my favorite Taiwanese fried chicken cutlet that I have ever had, maybe O2 even beats Taiwan! I always get the Chicken Cutlet here and really recommend getting the À la carte version since they give SO much chicken!!! Chicken Cutlet - The chicken is always so crispy and flavorful here. The white pepper flavor with salt is an iconic Taiwanese fried chicken taste, and O2 does it so well. The bento is pretty good too and huge! It comes with vegetables, rice with minced pork, and some noodles. You WILL have leftovers! I definitely recommend coming to O2 if you are visiting the Bay Area, the chicken cutlet is a must!

    Favorite Taiwanese bento box! Amazing fried chicken here. Small restaurant in tight plaza with parking all around. They have tea here as well but stuck to my usually spicy grilled chicken bento box. The spicy grilled chicken bento has a small kick to it with sauce marinated around it. It has a light crispy batter around it so not sure why it's called grilled. Comes with rice, boiled egg, and 2 sides. Have had different sides on different days. Popcorn chicken with garlic was great and has loads of garlic. Plenty of fresh garlic to make your mouth smell right after. Nice staff. Order takes about 10-15 minutes and perfect for to go. Quick and easy lunch with huge portion.

    R5 - boneless fried pork chop bento

    I wish I had tried this place sooner! This is some very legit and addictive Taiwanese comfort food. We tried a variety of dishes and they were all great. There's also a very generous amount of food, I would say that each bento can be 2 meals or for one very hungry person. In addition to the main meats, each bento comes with a lot of rice, sides, and veggies. All the fried foods were fried to perfection. Quick and easy online ordering system for takeout or delivery. Would definitely recommend this spot to anyone craving Taiwanese snack food classics.

    Popcorn chicken with Basil
    Yushi N.

    When I bit into my first O2 Valley popcorn chicken, I was amazed by how juicy the meat was given how crispy the exterior was. The chicken katsu in the bento was equally succulent. Paired with garlicky broccoli, braised egg, and a generous portion of rice, the food was amazing given the price point. One bento could likely feed two people - that's called a great deal. The interior of the store had relaxing plant motifs, including a mossy panel on the wall. Why the store is called O2 Valley is not clear to me but the refreshing, nature-y aesthetic was very relaxing to dine in. Most importantly, the service was super nice :') Idk the cashier just genuinely wanted to help, offering to show pictures of the food, bringing extra bowls to the table, etc. He seemed like a good boy pat pat.

    Minced pork bento
    Linda M.

    I've lived nearby for a long time and never stopped in. They're located in a small plaza with not too much parking. I typically just walk to this plaza. It's a pretty cozy shop. There's a good amount of seating inside. You seat yourself and order by QR code. Water, utensils, and condiments are also self serve. I'm sure you could probably order at the counter as well but I've never done it. We got a minced pork bento and a stir fry basil chicken bento. The chicken bento was pretty spicy, I liked it. The chicken was cooked very nicely and you get two sides and an egg as well as rice with minced pork. The minced pork bento comes rice, egg, and two sides. The staff brought our food to our tables for us. They come in convenient bento boxes and you can ask for lids and bags at the front should you need them. The portions are pretty generous. I ate maybe a third of mine. My partner finished his bento. Depends on your appetite. This is a great place when you just want some comfort food at a no frills mom and pop shop. They're not a big chain and are locally owned!

    Grilled Chicken Cutlet Bento
    Lawrence C.

    While I was in San Jose, a friend of mine suggested a Taiwanese bento place that I could check out since he was a big fan of it. I decided to order it on Uber Eats since I wanted to try it for lunch that day, and it was delivered fairly quickly with no hassle. I decided to try out the grilled chicken cutlet bento, since people online said it was better than the regular fried chicken cutlet since it's first fried and then grilled with additional sauces added. The portions of it are pretty sizable, and I was a big fan of the sauce along with the crispiness of the chicken. The meat was quite tender as well, while the sides were good as well. I decided to get their milk tea too, which also was pretty solid. Overall, I would definitely order from here again and I can see why my friend recommended it!

    #R6 Braised Pork Chop Bento (Boneless) 滷排骨便當
    Amanda M.

    I came here for lunch and got their Braised Pork Chop Bento 滷排骨便當. I was surprised with how many pieces of pork chop they gave, 5 pieces! The portion size for the bento is good, enough for 2 meals for me. The rice had a braised pork, then came with a seasoned soy sauce egg, and two sides. The sides vary - this time I got cabbage and carrots stir fried, and some type of meatball (pork ball) and celery mix. Overall, food came out within 5 mins of ordering. Everything was very quick and delicious. Parking can be a bit difficult but they have some parking at the back of the building.

    I came here twice, and here is my experience: 1. Ambience (4/5): The restaurant isn't too big but has plenty of seating. It's very clean and well-organized. 2. Service (4/5): I mostly served myself because there was only one worker handling both the cashier and server duties in the front. The lady in the kitchen brought the food to my table when it was ready. The guy at the counter was very helpful and nice when I asked him some questions about my food. 3. Food (4/5): - Grilled Cutlet Chicken with Rice (4/5): I thought it would be grilled chicken, but it was actually a big piece of fried chicken with a crispy coating. It was still delicious with the rice. The chicken had a crispy crust and was topped with sauce. I was very surprised by the huge portion, it could easily feed two people! I think the owner focuses on food quality and portion size, which might be why there are only a few workers. The bento box also came with a side of stir-fried vegetables and some braised pork. - Curry Rice with Fried Chicken (4/5): It came with the same fried chicken. The curry sauce was flavorful and pretty good. I'm not usually a fan of curry, but this one was fine for me. Overall: Service was quick and mostly self-served. The food was affordable with huge portions. Everything tasted flavorful and delicious. I'll definitely come back soon!!!

    #A4 Garlic Popcorn Chicken
    Donna D.

    Tried O2 Valley and really enjoyed it! I had their garlic popcorn chicken and loved how much garlic they put on it. So crispy and flavorful and it really hit the spot. I also liked that you can serve yourself dipping sauces which makes it fun to mix and match. It is a nice place to chill and hang out. For drinks I got the mango yogurt which was creamy and sweet and the jasmine milk tea was tea forward which I love. Definitely a solid spot for good bites and drinks.

    #R4 Popcorn Chicken Bento 鹹酥雞便當
    Ron P.

    First visit here and this place is da bomb!!! Self order and prepay from the table, and the food came out (not joking) in like a minute. I got the popcorn chicken bento and for around $17 the portions were huge!! The side dishes (veggies and noodles) were sooo yummy and I really enjoyed this no frills dining experience with amazing food :)

    Matthew C.

    Great portions, great vibes. Food was flavorful, the crispy stuff was crispy but still juicy. Pork belly was a bit dry and lean. Overall super solid eats. W Josh for the rec.

    Incredible vegan spicy red oil sesame noodles!!!!! (Look for "The Works, night market fave" on the…read moremenu). Surprisingly, the normal Dan Dan noodles ("special sesame dry noodle") were quite bad. The beef and tendon noodle soup is not bad, decent for when I was sick. There is a "beef and tendon noodle soup" as well as a "beef only noodle soup" on the menu - you might think the beef only one would be better value and have more meat, I ordered both to see the difference - even though the meat only one does have more meat, the meat is more tough and very hard to chew. So the beef with tendons soup has way better texture and more tender meat pieces

After placing our order, the food came out relatively quick. We ordered 2 beef noodle soups, the works, and 2 beef rolls. Starting off with the beef rolls, these came out cold. I heard that this is what this place was known for. The meat in our rolls wasn't even lukewarm and the pancakes came out super soggy almost like they didn't even try. Please tell me how the pancake look brown and crispy on the outside and still comes out cold and not crispy at all. My nephew even said they weren't crispy and he's 3. The lady told us that the sauce on the inside was salty and that's why they don't give extra and man was she right. 1/5* The beef noodles soup itself flavor wise was good and portion wise it was good for $21, but my noodles had no chew to them at all. I was attempting to pick them up with chopsticks and they would just break into pieces. They do give a decent amount of beef though in this. 2.5/5* for the flavor but don't expect much from the noodles. Same thing went for the works, it was a peanut buttery sauce that the lady claimed wasn't spicy, but my parents noticed that it had a kick to it even though they asked for it not to be spicy. The egg is a nice touch but not too sure if it's worth the price. Noodle consistency was the same as the beef noodle soup. 2.5/5*

P balanced. Pig ears had good woody spices and seaweed had solid garlicky sea flavor. Fish was light and soft with scallion ginger aromatics. Tofu quail egg was just sweet sour. Sauce bit watery. Rice porridge was lowk great depression food (Hella water, a few sweet potato pieces saving it by a bit) Good if it was 35% less.
