The best information regarding the stores and services, including the variations on each shop's items by what game is played by your shopper, I believe is Serebii's page on the avenue. It carries pretty much everything required for it, including the recommendations for people walking the avenue in both languages.
Something that isn't mentioned on that page though that I've just found out from general browsing of sites and also through my Japanese version is that once the avenue obtains eight rank 10 shops, the entire avenue gets what looks like a 50% discount across all goods for a week.
