Dead Rising 2

Go into each shop and make sure that the name shows up in the bottom left of the screen before you leave. All shops are light blue on the map and tend to follow the numbering below, with the exception of Royal Flush Plaza, which has some weirdness in the middle.

"N111 - Juggz Bar & Grill Kiosk" did not display its name when I went in, so I am unsure if it counts, even though it's listed on the map as a shop, easy to head in there through. dont need the kiosk only the restaurant
