The plan for Metropolis (10 Dunas East) was to include these kinds of tourist traps with Disney being the anchor tenant. The roof of the building was engineered to hold rides like a roller coaster and a drop zone type attraction. Virgin was also a tenant. Both dropped out when the original developer, PenEquity, proved incapable of building this thing on time. I agree with Alvin on the need for a district wide theme. It's already part way there with the black YONGE posts and they attempted to spread a template on sidewalks that extended the granite from the square to stripes along Yonge but this didn't catch on or remain enforced. There are plans to redesign Yonge with wider sidewalks with a unified design.
