The miso black cod at AQUA by El Gaucho is a high-end take on the classic dish, with a thick portion of black cod roasted in a savory-sweet miso sauce.[15] The kitchen emphasizes a polished presentation, often pairing the fish with seasonal vegetables or a smooth starch so the sauce and cod remain the focal point.[15] The fish itself is very tender and rich, and the miso sauce is abundant enough that diners can enjoy it with every bite, sometimes wishing for extra spoonfuls to capture all of it.[15] Comments from guests frequently highlight this plate among their favorites at the restaurant, noting the depth of the miso and the luxurious texture of the cod as reasons it stands out on the seafood-heavy menu.[15]
