I was here years ago, then it was closed for a while! [[HIGHLIGHT]]I was ecstatic when I came to find out it reopened... The vibes is the same[[ENDHIGHLIGHT]]. I haven't tried all the food, but what I have tried I've really enjoyed with the exception of today which is why I only gave it 4 stars. There's plenty of room for improvement, for starters the menu. If you've never been here imagine only the name of the plate with NO description, NO photos. Imagine trying to remember it all as you ask about any or all of them. It's frustrating. I will attach photos and reviews What I didn't like was the empapelado. It was basically seafood steamed in foil packet with melted cheese! It lacked seasoning and flavor! The tortillas they served with it were nasty textured and flavored. read more

Decent restaurant with good seafood. The servings were well portioned. We actually finished all our food. The ceviche had a great balance of citrus! I usually have to order extra limes on the side to add more of the citrus flavor, but didn't need to with their food! The service was good enough for a big party, but nothing amazing. They were a bit busy so I didn't expect perfect service. The ceviche mix had good portions of all the ingredients and even the shrimps were a good medium size. All prices were $18 and above. Only thing I disliked was they ONLY serve drinks in bottles. Water, sodas, even your agua frescas are all served in water bottled-type of containers. The horchata was too sweet for my taste. The agua de Jamaica (hibiscus) was ok. Just make sure to double check your check. Street parking. Overall, decent place. Try it for yourself and then decide. read more

[[HIGHLIGHT]]The vibe is good and the seafood is fresh, but they don't clean the shrimp.[[ENDHIGHLIGHT]] 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. read more

They close at random times and never answer their phone. Even though the seafood is good, it's pricier than other spots and I'd rather give my business and referrals to a more professional establishment who cares about their customers. read more

Literal best, fresh sea food in Pomona. My go to spot. Highly recommend!!!! Nothing like this in Covina. 10/10

Hands down the best mariscos I've ever had in the states, they're perfect, you don't need to add anything unless you want it spicy, aguachile rojo is chefs kiss!! Perfect amount of spice, the chilpetines really enhance the taste and the shrimp is well cooked in the lime juice and that mayo on the tostadas yum, My mouth waters every time I think about it. lol.

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. read more

Their seafood is fresh and has a great authentic taste. The green aguachile shrimp with octopus was amazing. Spicy but oh so good

Worst Mariscos spot, worst service I have ever experienced, took 20 min to come greet us with a menu, then took another 30 min to bring us our ceviche, found a piece of latex glove in my ceviche and the manager said it happens, didn't offer anything to accommodate the piece of glove in my food. If there was a no star rating I would of used it. read more

Food is amazing! Flavor is amazing! They were out of avocado so we went to the store to buy some!

Let me tell you this is not your ordinary marisco restaurant. This place is meant for real Marisco lovers. They are know for their large platters of mariscos which are so good. I can honestly say this has to be in my top 3 marisco spots. Their seafood taste so fresh and are made with a great presentation. The Botana 30/30 feeds between 4-5 people depending on their appetite. Their oysters are so fresh and tasty great flavor overall. Service is very good as well the girls are busy but they do be checking up on you to make sure everything is ok or if you need anything else. I would definitely recommend this place for seafood lovers. read more

Used to be my spot to go too Now waitress are horrible I used to feel welcomed in this place not anymore. The waitress just look at you like if you owe them something. They don't welcome you or communicate with you at all. Ostion you were the best place to eat mariscos before now is BAD!!! read more

My gf and I have been coming here for years, we normally get cucarachas shrimp which we highly recommend. In the photos we ordered 3 plates which came out to $42 ! Quesadilla de Camarón, tacos de camarón, and half dozen loaded oysters. The oysters are huge by the way. Oh and no aguas frescas (Jamaicas, horchatas, agua de piña) are served here which is a bummer. Regardless, food is always fresh as it should be. 4/5 stars due to pricing and lack of beverage options. read more
