Nanzen is a basement Japanese izakaya in Kitahama, Osaka, a one- to two-minute walk from Exit 2 of Kitahama Station. At lunch it serves sashimi, fried dishes, grilled fish set meals and other items, and in the evening seasonal fish with Japanese sake. The lunch set menu is large and the space is wide enough for groups of about ten and for larger reservations. All seats are smoking, which is uncomfortable for anyone sensitive to cigarette smoke.
