Mariscos Rio Balsas — a Lincoln Square seafood find that regulars keep close. The cocktail program is serious. Friendly without hovering, and open late. "It was pretty empty but we had amazing service, the food was fresh with large portions" — Naiomi Arguelles [$$]

🌙Late night — the kitchen runs past 10.

Una experiencia espectacular de principio a fin. Cada plato refleja el cariño, la dedicación y el orgullo que Alex pone en su cocina. La presentación es impecable, llena de color y atención a cada detalle, y el sabor supera las expectativas. Los mariscos son frescos, perfectamente preparados y con un equilibrio de sabores que demuestra la pasión detrás de cada creación. Gracias, Alex, por hacer de cada visita una experiencia memorable. Se nota cuando alguien cocina con el corazón. ¡Totalmente recomendado! 🦐❤️

Wanted ceviche late at night and this place was open. Very friendly staff that wants you to enjoy their hospitality and good food. The ceviche was good and the portion is generous. They brought an extra flan on the house which was a special gesture. Will be back for the food and the amazing service equally

Mi novio y yo fuimos por primera vez a celebrar mi cumpleaños y quedamos encantados! Desde que llegamos, Alex nos atendió de una manera increíble! Súper amable, atento y con una energía que realmente nos hizo sentir bienvenidos. Nos hizo sentir como en casa y tuvo detalles muy lindos que me hicieron sentir especial en mi día. La comida deliciosa, el ambiente muy agradable y el servicio de primera. Sin duda lo recomiendo al 100% y ¡definitivamente volveremos pronto!

We showed up tonight and were extremely impressed!! It was pretty empty but we had amazing service, the food was fresh with large portions. Even the inside was beautiful! The owner (I think) came out and let us know they just opened 5 months ago so come out and welcome them to the neighborhood! They’re open late too ❤️

Manejé dos horas para probar este lugar y me pareció muy bueno. Me encantó el ambiente. El personal fue muy amable y el precio de los mariscos no estuvo mal. Les recomiendo que lo prueben; la sazón es excelente.

We got a seafood plate called levanta muertos and it was delicious! I highly recommend this spot if you love seafood.🍤 Service was also good she was nice and recommended the plate. The small fed me my mom and my son.

Brand new-ish Mexican restaurant that specializes in seafood. Tried both of their ceviches, their seafood cocktail, and shrimp soup. The food is way better than I can describe it. The taste is authentic, the salsa will make you sweat, but the variety of amazing looking food may cause you over order like we did. Our little corner of Irving Park/Albany Park needed something a little different and Mariscos Rio Balsas is definitely it. We were headed to Garcia’s and came here instead. Maybe it’s a new neighborhood favorite.
