Kua Aina Sandwich Shop is on the B2F food court of Lucua Osaka in Umeda, Kita Ward, Osaka, and serves Hawaiian North Shore-style burgers and sandwiches. The signature burger uses a thick meaty patty with avocado and cheese, and it comes with fries. The burgers are large enough to be hard to hold with one hand, and set orders are available. Prices run high relative to the portion size.
