    El 30/30 delicious
    Cinthia C.

    The food is delicious. We ordered a platter I think it's called 30/30 it was $60. No complaints on that. NY mother in law got Mojarra( fried fish. That she loved as well. Th service sucked again. The first rime we went there the waitress left. This time, the waitress aren't smiling,just dropping stuff the food, just rude.I always make sure my husband tips we'll, this time I didn't care. I felt like I was chasing them down.

    Chicharones de pescado and quesadilla al gobernador!!!

    This place has some of the best seafood dishes in town. Every item I've ordered has been delicious . From their tostadas, aguachiles, ostiones preparados, chalupas!!!! Anything you order is a hit. Seafood is fresh and now their staffs are up to par too. All the staffs are attentive and quick to provide service. Will definitely be back again and again!!!

    Vein of poop

    The vibe is good and the seafood is fresh, but they don't clean the shrimp. Every one still had the black strip (poop vein) inside. For a mariscos spot, that's a basic fail. Hard to enjoy the food after noticing that. El lugar tiene buen ambiente y mariscos frescos, pero no limpian los camarones. Todos tenían la vena negra (el intestino) todavía. En un lugar de mariscos, eso es imperdonable. Difícil disfrutar la comida así.

    Aguachiles
    Shelby P.

    The seafood here is so good and so fresh it is literally amazing. Service is great and everything came out really fast. Favorite seafood and aquachiles spot hands down 10/10

    Este lugar merece 5 estrellas es lo mejor de lo mejor , el servicio es rápido , los mariscos frescos el ambiente muy bonito ! Amazing ambiance , food and service ! Fresh !

    Oysters
    Carolina H.

    The seafood is incredibly fresh. We especially love the oysters, shrimp cocktail and ceviche. The service has greatly improved since the restaurant's reopening, making the experience even better. It's easily one of the best seafood spots in Southern California.

Tuna Tostadas are also delicious ( a bit over sauced ) but very, very good. Wood paneled ceilings, grungy noir chic design, downstairs lounge & hip music give it a 2026 Great Gatsby vibe.

Mango habanero shrimp ceviche, also outstanding, I generally prefer fish but this was really delicious with just a tiny bit of heat. Tuna ceviche made with yellowtail, also very good. Really you can not go wrong with any of these. Will be back to try the green shrimp which I believe is more of a traditional aguachilie. Also had oysters and the fish taco, both were very good. I generally don't get fried fish tacos but was told that it was good. And yes lightly battered with great flavor with the cabbage and sauce. I thought the tortilla it came on was average, but overall a great fish taco. It is in a bar, which for me I really liked. The owner was very friendly and obviously cares about his food which you can tell with the quality and taste. Will be back here for sure.... Best ceviche I have found recently, all of the flavor profiles on the 3 different ceviches we had were totally different and all great.

From the moment we walked in, the staff was super welcoming and took the time to walk us through the menu and their specialties, which made ordering a lot easier. The shrimp tacos were a pleasant surprise--not your typical style. They're fried and topped with a flavorful sauce that really sets them apart. Solid choice if you want something a little different. The real star of the show was the Poseidon botana aguachiles. We were originally deciding between the Poseidon and the mixta, but they mentioned they could make the botana a Poseidon style, and that's what we went with. Absolutely delicious--super fresh and packed with flavor. Highly recommend this dish. We also tried the tostada de pescado (size small), which was probably my least favorite. It wasn't bad, just didn't stand out compared to everything else. I'd personally skip it next time. One thing to note--there's a small parking lot that was more full than expected given how many people were inside. It seems like it might be shared with nearby businesses, so just keep that in mind. Overall, great experience, great food, and I'd definitely come back to try more from the menu.

    Food was fine, but the service needs a lot of work…read more It was our first time coming here, so I had no idea how anything worked. When we first arrived, the front was completely disorganized, and there were no lines at all. People were just crowding around the hostess table, so I had no idea how to add my name to the waitlist. There were no signs that showed where the line starts, and no line was being formed at all. The hostess kept having to walk people to their table, so it was nearly impossible to grab her attention. When I did manage to do so, she was very rude and prioritized other people before us. She obviously saw us come in before other people, but ignored that fact and just added other people to the waitlist first. Ridiculous. Their waitlist system is through Yelp, which sends you a text when your table is ready. Based on the app, it said that our table wouldn't be ready for about 1.5 hours, so we decided to walk around the outlet in the meantime. After nearly 1.5 hours, I saw that we were 2nd in line and decided to have our family walk back to the restaurant. While we were waiting outside for me to receive the text, we heard the host call my name and say that our table was ready. We met with him, and I said that it was odd since I hadn't received the text yet. He said, "Oh no, the hostess told me about you guys. You said that your phone was dead, so you'd hang around the restaurant and wait for us to call your name." No. We never said that. They have us confused with a different party. This means that if I hadn't checked the waitlist regularly and had just waited for that text, it never would've come, and we never would've gotten seated. What a messy system. Also, I've never been to a seafood boil restaurant where we have to ask for the bibs. Normally, they're given to us right when we're seated, so it was weird. We noticed other people were given bibs right when they're seated, so we're not sure why this happened. Other Kickin' Crab locations also give you an entire bottle of ketchup, whereas this place only gives small plastic cups. Weird. I think the employees and other customers would agree with me when I say that the entire place is completely disorganized because multiple orders around us were being messed up. The table to our left was missing its piece of corn and sausage in its bag of shrimp, while the table to our right was missing crawfish in their bag. The workers were obviously trying their best to straighten things out, but it didn't seem to be working. The menu is consistent with their other locations, but the market prices are a bit higher than what we're used to. Compared to the location that we always go to, this place offers bigger frozen crawfish, but the bags were mainly just the claws, so it seemed like a big ripoff. * Cajun Fries: 8/10 - nice cook, but there was only cajun seasoning on the top * Shrimp (Head-On): 9/10 - good flavor * Crawfish (Frozen): 6/10 - big crawfish, but the bag was mostly just claws and not enough garlic The place is located at the Shoppes of Chino Hills outlet, so parking is relatively easy. After being seated, the servers were nice, but it was difficult to enjoy the experience because of everything that had already happened. Overall, the service was a huge letdown, and we did not feel comfortable eating here. Places like this are why tipping is optional. The workers at the Kickin' Crab location we usually go to are way more laidback and friendlier, yet still maintain impeccable service. Would not return.

    What a unique experience!…read more Grilling, bbq-ing, etc is a norm but steaming your food on the table? Now that's something else! I really enjoyed the dinner I had, they offer lots of options, from freshly made buns, dumplings to fresh seafood. The menu is pretty extensive and they also offer cooked dishes from the kitchen. The staff are very helpful and friendly. They made sure we get the best experience as it was our first time dining at this place. We had the big eye fish as they called it and they steamed it at the other empty table because our buns and dumplings were steaming at the same time to save time. They finish the fish at the kitchen with the hot oil and sauce. We also had the pork and shrimp buns, and beef dumplings. They were delicious! You can make your sauce at the station too and they provide good options. We also got the baby oysters appetizer that was soaking in some sort of light soy sauce marinade. Also got the soft shell crab and you get 3 whole crabs for $10! It was so worth it! The whole restaurant looked clean and inviting. The booths were spacious. I would definitely come back here and try other dishes!

    Came to YOUPENG Seafood recently and overall had a really enjoyable experience…read more The crab was fresh and beautifully presented. The meat was sweet and tender, and the sauce had a nice balance of savory flavor without overpowering the natural seafood taste. You can tell the quality of the seafood is solid. The sea urchin egg custard was super smooth and silky. The uni added a rich, slightly briny depth that paired really well with the delicate steamed egg. Definitely a standout if you like uni. Each dishes had its own highlight. Ambiance is modern and clean, giving a slightly upscale seafood house vibe. Service was decent and the food came out nicely presented. Prices are on the higher side, but for fresh seafood and quality ingredients, it feels reasonable for a special meal. Would come back again to try more of their live seafood options.
