I popped in this morning for the breakfast buffet and bottomless mimosa brunch and let me tell you it was everything and more. From the person that answered the phone when I called to get the hours, to the waitress everyone had excellent customer service. And the food Baby the food was phenomenal. Not to mention the fact that they never really let my mimosa glass get empty. I appreciate that. Will this be my new Sunday spot? Yes! Yes it will

Came here on a Thursday and had 4 quesabirrias because I don’t eat seafood. They were AWESOME, best I have ever had. Wife had the “small” ceviche which she could only eat half of, and she said it was great. Definitely worth giving this place a look. The other seafood options on the menu look great, and we will be back next Thursday.

My friends and family visited Mariscos El Costeno this evening and we all had a pleasant experience Mariscos El Costeno brings a different spin to seafood. They bring their own taste and style to every dish they prepare and make sure to incorporate the Veracruz style of seafood. The atmosphere/ music was enjoyable The pina colada I had was made perfect! Also, the service we received was very attentive and friendly. If you are around the area, make sure you stop by and try their delicious food!
