    Best bento shop to go! The staff is so kind and accomodate my request. They are so helpful and friendly. The most important is the food is delicious in a lot of portion. I cannot recommend enough! .

    #A3 Basil Popcorn Chicken
    Juliet T.

    This is a good spot to grab a snack or box for lunch! I had the popcorn chicken as a snack before dinner. The chicken was crispy and seasoned well- can't go wrong with this as a snack!

    Came again with my mom this time and decided to try everything on the menu. The spicy katsu chicken bento box is still my fav. The grilled chicken is also very good. The fried tofu and eggrolls are really good. The fried squid and sesame balls were just ok. The milk tea was just ok. Nice place to come that it is very causal for downtown Palo Alto.

    #R10. Pork Belly Bento
    Maria G.

    This is like Taiwanese comfort food for me. They have spaces to eat. It's very casual. Staff is mainly at the counter. You go to the counter to order and you can sit anywhere. We have mostly ordered to go. But I can see the restaurant part have very basic service. The staff is very straight forward. Not a lot of fluff but not bad. Their food comes out piping hot! The chicken is super crispy. Flavor is good. The side dishes are tasty. Portions are big. One order can easily feed 2 people. Great bang for your buck. We will be back for sure.

    Garlic Popcorn Chicken
    Derek S.

    Came by the other day to grab a quick bit and it was a surprisingly decent experience. Ordered ahead via their website and my order was ready upon arrival. As O2 Valley is towards the beginning of the University Ave business district, parking was pretty easy a couple blocks away. To my surprise, the venue was empty upon arrival and I was greeted upon arrival and was back outside within 30 seconds. Ordered the garlic popcorn chicken and it was surprisingly fresh, hot, and flavorful. There was a a ton of garlic on top too!

    #R14. Thai Spicy Fried Chicken Bento
    Nishika T.

    Just went by this place with a friend and the food and service came out very quickly. The serving size was really large and we both took our leftovers home. My sauce came on the side, which was great to keep the chicken crispy for leftovers. The ambiance isn't as cute sadly. It's a place where you order at the counter and have to get your own water, etc.

    Garlic Popcorn Chicken
    Joyce K.

    Garlic popcorn chicken, a garlic lovers dream!! Dropped in ~4:30pm on a Saturday for some popcorn chicken. Aside from the three tables already eating, the place was fairly empty. Service was pretty quick. Once ordered and a trip to the restroom was made, my order was ready. Sauce bar was stocked with sriracha, sweet and spicy chili sauce, and their in house spicy mushroom sauce. Pepper and chili pepper powder are on the tables. Aside from order to go at the register, a lot of things seem self served. Utensils and napkins provided on the tables for dine in. QR code for menu and ordering is also on the table, presumably for dine in. Popcorn chicken was good-- crispy, juicy, and piping hot. Paired with the extra sauces and seasoning dusts found on the tables, this is a great snack! Garlic version came with copious amounts of garlic, which is a plus! But if you're not a fan, basil popcorn chicken is also on the menu. Will return!

    #R8. Taiwanese Sausage Bento
    Tansy W.

    Small casual Taiwanese bento box spot. Came here for lunch and got the Taiwanese sausage bento box, which was fine but I much preferred the chicken with basil bento box that my friend got. Will have to get that next time! They also have bubble tea with salted cheese.

    The painting on the wall is tilted ): which pissed me off a little. make you get R2 fries chicken fillet bento if it is your first time. It is my favorite chicken fillet bento in the bay. Toilet: 3/5 Food: 5/5 get the R2!!!! 不服來辯

    #R6. Braised Pork Chop Bento
    Kat Z.

    Awesome little Taiwanese bento spot! Not a lot of Taiwanese options these days. I got the braised pork bento, which was fair in both pricing and size. This lasted me for two meals The only comment I have is that the food is quite oily. After eating all the bok choy and even the tomato egg, the amount of oil is quite a lot... especially that bok choy.

    First time at this location. The Q5 with 75% sweetness is actually so good. As someone who's not usually a fan of boba, I really enjoyed my drink. Their crispy tofu is pretty bland. The garlic popcorn chicken was flavorful, but I wish there was less garlic and a little more chicken. The service was pretty fast. The ambiance inside is nice & clean. A cool place to hangout and get snacks.

    R2 - Fried Chicken Cutlet Bento
    Belinda C.

    I really loved the Fried Chicken Cutlet Bento that came with Minced Pork Rice, a Marinated Egg, and the two sides of the day: Tomato Egg Stir-Fry and Sauteed Cabbage with Shredded Carrots. Tastes like popcorn chicken. Crunchy batter that's fun and satisfying to eat. Generous portion of chicken. I love stir-fried tomato and scrambled eggs. I thought about asking if I could order that as a side to go. I enjoyed the cabbage. The marinated egg didn't have much flavor. From my photo, you can see that not much marinade permeated inside the egg. I am still happy to have the egg to eat. Perfect timing given it was the day before Easter! Because it was a holiday weekend, I bumped into two other Sacramento Yelp Elites, Arnel and Erly, who had also traveled to the Bay Area. Ha, they spotted me taking pictures and video around the restaurant! At 3 PM, several restaurants may close and take a break, so I think that may be why all of us ended up at the same restaurant! We have similar foodie tastes and use Yelp to choose where to eat. We all agreed that we wished Sacramento had a yummy Taiwanese restaurant like O2 Valley. Maybe we do with Taiwan Best Mart??? I should go check it out with them. Service was fast, polite, and helpful. Restaurant is clean and simple. The Chat GPT generated artwork of O2 Valley engineers is amusing. I think by requesting that they all be eating bento boxes turned them all Asian! If you're hungry in downtown Palo Alto, go grab something fun to eat and drink at O2 Valley.

    Garlic Popcorn Chicken and Lemon Green Tea
    Arnel E.

    We were in Palo Alto visiting our daughter at work. During her 3pm lunch break, we happened to pass by this Taiwanese restaurant as we were strolling along University Avenue. This was the ideal spot for us as we were planning for a quick bite at a counter service place with snackable items. Simply furnished, this eatery has posters of their featured menu items and a curios or "timely" ChatGPT generated art that AI might perceive of O2 Valley. I failed to take a photo of said framed image. For drinks, we got the Taro Milk Tea, Oolong and my Lemon Green Tea. I chose 25% sweetness, no ice with aloe mixed in. It was a weird & bitter tasting refreshment as I thought the tea to lemon ratio was out of whack. I finished it anyway. It was an acquired taste kind of drink, I guess. For eats, we shared the Garlic Popcorn Chicken, Hundred Layer Tofu and Crispy Tofu. The latter being unseasoned definitely needed the sauce that came with it. I spiced up this same sauce with the excess garlic bits that came with the chicken. We also happened to see our fellow Yelp Elite from Sacramento, Belinda. She was in town also to visit family. That's one happenstance we wouldn't have thought to happen this Saturday afternoon. We would've tried the generously portioned bento boxes if we were that hungry. A reason to return.

    Food and experience is closer to 4.5 but rounded down bc it's so expensive…read more Was curious to try this new restaurant specializing in Peking duck. Reservation was easy to make over the phone and you have to preorder duck ahead of time. We also got pan fried buns, bok choy, and mandarin fish. Dishes are expensive but good quality. I read mixed reviews about the duck but I thought it was great - crispy skin and relatively tender/juicy meat. It is the first time I've seen an extra charge for the duck pancake wrappers; it was not a pleasant surprise but at least they were thin and delicious. We opted to have a soup made from the leftover duck and that was delicious. Service was also pretty good; they even packaged the leftovers for us. Highly recommend for a special occasion or to impress friends but too much of a splurge to go to regularly.

Unfortunately, the experience was pretty underwhelming overall. The Peking duck was definitely the highlight of the meal -- crispy skin, flavorful, and probably the only dish I'd genuinely come back for. But everything else missed the mark for me. We ordered the string beans, salted egg corn shrimp, xiao long bao, pork buns, cabbage dry pot, and black pepper beef. Most of the dishes lacked flavor and were noticeably oily. The pork buns were especially disappointing because the dough was overly thick and dense compared to the filling. The biggest letdown was probably the black pepper beef. The meat quality was really poor..a lot of chewy pieces with tendons, and it was hard to enjoy because almost every bite felt tough. Definitely not what I expected from a restaurant with this reputation. Overall, aside from the duck, the food felt heavy, bland, and not very balanced flavor-wise. I really wanted to love this place, but it didn't live up to the expectations for me.

We enjoyed every dish! The chongqin spicy noodles, the salt and pepper shrimps, the sizzling cumin lamb, the fish in chili oil. Yum yum yum! We ordered the hottest version but it was not too spicy for us - it was very flavorful. The fresh cut red chillies they give you, was really spicy - the red bean spicy sauce was just right. We enjoyed the cool beers with the spicy food. It's a unique ambience for a Univ Ave restaurant- it's just a Chinese kitchen serving good food - like you came to a home and got served really well.

This is probably the only Chinese restaurant around here with such an inviting outdoor patio, which makes it perfect for us since our dog babies can relax too. The menu strikes a really smart balance between authentic Sichuan spicy dishes and more Americanized Chinese classics, so there's something for everyone. The signature spicy fish fillet in flaming red oil is a must-try -- bold, fragrant, and so satisfying it might have just saved me an expensive flight back to China. The chili oil wontons are my personal favorite starter and never disappoint. This is an easy repeat spot for us, and we'll definitely go back around CNY days.

There were various dishes on the menu with appetizers, different proteins, carbs, etc. We had already looked at the menu prior to coming so we were able to place our order fairly quickly. Thick stir fried noodles: The noodles were pretty good! They were a mix of bouncy and chewy with small slices of chicken and bok choy throughout the dish. It was quite oily though. Spicy wontons: I thought these were going to be soaked in a peanut sauce but it was definitely more of szechuan chili oil. Maybe I read the description wrong. The wontons were tiny but plentiful. These were just okay, the pork filling was bland. Pan fried dumpling buns: The buns weren't as crispy as they're supposed to be. They had a small amount of pork filling but good soup inside. Be careful biting into one because it was hot. Sweet and sour chicken: Our favorite dish out of everything! It was the perfect combo of sweet and sour. There was more than enough chicken and gave us leftovers for another meal. I enjoyed the extra textures of the bell peppers, onions and pineapple throughout the dish. Definitely recommend! Service was as usual for a Chinese spot. There's a small private room on the right side if you have a reservation for a larger party.
