Sanmaruku Cafe Nankai Tennoji is on the second floor of Mio Plaza in Tennoji Ward, Osaka. It serves coffee, bread, and parfaits, and the matcha parfait comes with chewy rice cake, ice cream, and matcha sauce. The cafe opens at 8 a.m. and has 96 seats, and customers take a seat first before ordering at the counter. It gets crowded depending on the time, so groups of three or more have trouble finding seats.
