Kashi, which also has a branch in Huntington, is a jazzy addition to mondo sushi. Major rolls include twister, with white-tuna tempura and spicy lobster; Sunset Blvd., with tuna, salmon, yellowtail and avocado in a seaweed wrap; and takayama, starring spicy tuna.


Glittery and sharp, Nisen sushi is a tribute to curves and swirls. Scottish goat brings in seared-ginger scallion, goat cheese, jalapeño salsa and a balsamic vinegar-mirin glaze; fisherman wharf is lobster, whitefish, jumbo sweet shrimp, pine nut, mango and beer dressing.
