In episode 18 of Hanasaku Iroha you can see a café called Caffé Arco di Campagne, so I went and took a look.

The café is inside this Prego Shopping Arcade which Ohana ran past on her way to Shiinoki Cultural Complex in episode 8.

I didn't get any coffee, but I did have some cake while I was here.

Down the street from the Parco Shopping Arcade is also this Daiwa Department Store. I've marked a path from Caffé Arco di Campagne to this place in the map below.
