Hawaiian concepts are rare on the mainland, which makes Ono stand out in the fast-casual crowd. The menu features a fusion of Asian cuisines with some American touches. Customers gravitate toward the popular $10 plate lunch, a Hawaiian specialty that features barbecued chicken, beef or seafood with rice and macaroni salad over steamed cabbage. Other island dishes also are offered as both family meals and single entrees. So far, Ono’s locations have been limited to California and Arizona.
