The cauldrons of seafood at Mariscos El Submarino are proof that ceviche season can be year-round if you know where to look. Owners Amy Hernandez and Alonso Guzman opened this Jackson Heights storefront in 2020, known as much for its mustached submarine mascot as its generous ceviches served with tostadas and saltines on the side.
