Everything was absolutely delicious especially the mariscos tower, it was incredible! The only thing I’d suggest improving is the steak fajitas; the meat quality could definitely be better. Overall, we really enjoyed the experience.

I found this place in Round Rock using google maps, I almost hesitated to check it out, but I’m glad I didn’t. The place is off of 79, I’m not sure if they have parking in the back, but they do share parking with other small shops. The place is clean, and they have plenty of seating available. The service is friendly and efficient. The food is very good, at least what I tried this time, which is a shrimp and octopus cocktail. They have a wide variety of different hot sauces to choose from. They also have a stage where they appear to have karaoke, and they also play Mexican music, this is based on the instruments on the stage. Check it out, you won’t be disappointed.

We tried this place after a friend highly recommend the food. He was right. We ordered both towers on the menu and really liked both. Service was great. Only drawback was the band. The music was extremely loud, our server couldn’t even hear us to place our order. We ended up pointing out the food on the menu. Wish we had a more relaxing meal, we ate and finished as fast as we could. Will definitely go back but need to find out when the bands not there, because the food is that good.

My first experience:
From the outside, Unos Mariscos o Que might seem like just another unassuming spot—but don’t be fooled. This is a hidden gem in Round Rock that seafood lovers must experience.
The moment you step inside, you’re welcomed by an open, clean, and well-put-together space that feels both inviting and thoughtfully designed. The atmosphere strikes a perfect casual and inviting balance making it an ideal place for a relaxed meal with family or friends.
Now, let’s talk about the food—incredible doesn’t even begin to describe it. The seafood is flavorful, and prepared well. Whether you’re craving ceviche, tacos, or a perfectly grilled fish fillet, every dish is crafted with authentic flavors and quality ingredients (again, my first experience). The seasoning is spot on, and the portions are generous without being overwhelming.
Service is another highlight. The staff is attentive, friendly, and quick to offer recommendations, ensuring you find the perfect dish to suit your taste.
If you’re a seafood lover, Unos Mariscos o Que is an absolute must-visit. Great food, welcoming atmosphere, and good service—it’s the kind of place you’ll find yourself coming back to again and again.

Overall, we had a pretty good meal here, minus some service issues. The seafood is definitely the star, good and fresh. Both the seafood tower and the grilled shrimp (cucharachas) were very good. The michelada was also quite nice. The service issues were probably language challenges as our waitress did not speak English, and our Spanish is limited, but they goofed up the kids orders, and had to remake them, which always creates the challenge of us trying to eat while the kids have nothing. That said, although wouldn’t rush back, could try again since the food was good.

This was my first time visiting while on a business trip. I chose this restaurant after searching for good seafood in the area. The food itself was excellent, but the service could have been better. The wait for our meals was longer than expected, and getting drink refills was difficult. Our waitress seemed more attentive to the table next to us than to ours

Great food. I ordered octopus well, cooked soft and juicy, generous portions,
Service needs more experience. There was a 10 people table, and everything looked like slowed. The bar we order beer it came late and the menu prices are diferent than what you’re charged no big deal Seafood fluctuate in price but a photocopy off your new prices helps until you get new menus.
The atmosphere is ok, but tvs with a frozen channel is no to appealing
Remembered sports attract customers no Mtv
Well, the important part is the food is goog

We won’t be back. I hope we don’t get food poisoning. I was excited to try this spot but there was no flavor in the ceviche. Plus our bacon wrapped shrimp was raw. We told our waiter named Leidy the bacon was raw in the inside and she said that’s how it’s supposed to be. I was like no way you’re supposed to ever eat pork raw.
The response I’m getting from the owner is a Complete LIE!! the waiter Leidy Never once tried to resolve the problem and never asked us if we would like them to cook it more, this place is unprofessional

Went to eat here because I was craving Hispanic shrimp cocktail. This place had the highest rating compared to other places so we came here. I ordered the shrimp cocktail and we also ordered the shrimp with rice plate. They both really good, I liked how they had a variety of sauces to choose from. They had music playing in the background, good atmosphere. The only thing we waiting a while for the food to come out. Other than that it was good
