Izakaya Aiyo is an izakaya in Minami 4-jo, Susukino Station, serving seafood direct from the farm and sake. It offers assorted hoe, aged hoe, grilled fish, jjangi, and ochazuke, along with a choice of mega highball. A 90-minute all-you-can-drink option comes with QR-code ordering, and the shop stays open until 1 AM with last order at midnight. Large groups fill the space, so the room is loud.
