Poppo Time appears to be situated in a major thoroughfare in Neo Domino City. Across the street from the Apartment is Cafe la Geen, Jack's favorite cafe.
Poppo Time looks similar to an old schoolhouse, made of bricks and whitewashed. A large dysfunctional Grandfather Cuckoo Clock is placed above the front door of the shop, with it's internal mechanism accessible in the second floor and the attic.
The apartment behind it has an underground garage which serves as the hangout and Duel Runner garage of Yusei and his friends. It is accessible to the street by a ramp.
