Seafood is the main event at Taco Sireno with fresh oysters, aguachile de camarón (marinated raw shrimp), yellowfin tuna tostadas and a mindblowing grilled cheese with shrimp just some of the sumptuous dishes on the menu. With decor transported straight from the 80s and a DJ spinning tunes in the corner, Taco Sireno is a low-key hidden gem.
