FIRST LOOK: Mariscos El Submarino opens in Park Slope
Husband-and-wife team Alonso Guzman and Amy Hernandez bring flavors of Mexico’s Pacific coast to NYC
Mariscos El Submarino is now open on 7th Ave - and after stopping by as their first customer today, I can already say it will be a neighborhood favorite.
You’ll find them at 226 7th Ave (between 3rd & 4th St - in the former Maya Taqueria space), bringing their acclaimed Sinaloa-style Mexican seafood to the neighborhood. The excitement has been building ever since Park Slope Pulse first reported the news in April last year, and the first appearance of their sign on 7th ave in November last year.
Mariscos El Submarino is owned by husband-and-wife team Alonso Guzman and Amy Hernandez, who bring family recipes and flavors from Mexico’s Pacific coast to NYC..
I had the chance to meet Alonso, who shared that the dishes are inspired by food in Sinaloa, a state in Mexico where his parents grew up. He also mentioned that it took a long time to find the right location in Park Slope (their fifth location) - a neighborhood he loves. His message to the community is simple: “Come visit us!”
I started with the Kraken taco - easily my favorite, beautifully presented and topped with succulent octopus - along with the Aguachile Verde, which is perfect for sharing (though Carlos’ favorite dish is the Aguachile Rojo, so try that and tell me what you think). The gleaming La Consentida tuna tostada was another fabulous dish.




I also ordered the La Makabra tostada, an indulgent mix of seafood piled high (because you deserve it!). It ended up being another one of my favorites and is definitely made for sharing. I paired my meal with a perfect margarita that had me dreaming of warmer days. Across the board, everything tasted fresh and full of coastal flavor - especially the chilled, refreshing La Makabra.
The whole team was warm, humble, and welcoming. Alonso, Danny (GM), Carlos, and staff give locals the kind of hospitality that makes you want to stay - and come back often.
Alonso also shared that they’re opening a Manhattan location soon.




Given the huge volume of seafood dishes I ordered plus a cocktail, the price felt reasonable and this comes across as great value for the neighborhood. If you love seafood and Mexican food, this is one to add to your list - enjoy (they’ll be open until 11pm tonight)!
