In the kitchen at Kai Sushi Asian Fusion, chefs set to work crafting diverse dishes from throughout Asia at the same time. In one part of the kitchen, chefs could be slow-grilling ducks to a crispy finish and sizzling up thin crepes to create the house's signature peking duck. Nearby, another chef could be sautéing lobster, jumbo shrimp, chicken, and roasted pork with a special sauce to form the Surf and Turf Kai Delight. But most of the staff spends their time carefully rolling together ingredients inside their signature sushi rolls. These combinations run the gamut from classic California rolls to more decadent options such as the Williamsbridge roll, a core of spicy tuna, yellowtail, avocado, and tempura flakes wrapped in soy paper and suspended across the East River.
