As I have opined before... World Indigenous Peoples Exposition (WInPEx)-- permanent, differently branded, unique to Edmonton, respectful of Indigenous contributions to society...
and loaded with "restaurants, cafes, farmers' markets, courtyard available for weddings etc." plus indigenous art, handcraft, entertainment and culture (broadly speaking).
I like the San Antonio reference -- both for the Pearl District and I would add the Arneson River Walk. Strong respect for Hispanic culture -- Edmonton could do the same with First Nations culture.
