About
Nikkei cuisine — which fuses Japanese precision with Peruvian ingredients — is a recognised Japanese culinary tradition that emerged in Peru's Japanese immigrant communities and was codified by chefs like Nobuyuki Matsuhisa. Koishii interprets this tradition through Peruvian Master Chef Kinyo, employing Japanese cooking techniques across a sushi counter, robata grill and hot kitchen. The result is tiraditos, nigiri platters, duck and Pisco cocktails served against a spectacular Mumbai skyline backdrop. Tripadvisor Travellers' Choice award holder, the penthouse setting alone ranks among Mumbai's most dramatic dining rooms.
