Okay, story set modern dayish (Dec 2000) in London. My characters are standing in front of Harrods in Knightsbridge and about to go in. Neither of them has ever been there before (or been in a department store, period). What's going to catch their eyes? What do the Christmas decorations look like? I've found images of the front of Harrods and a store layout, but neither one really answers that. They'd be coming in at street level, and any entrance will work.
I've googled Harrods, Harrod's, and British landmarks, and they've been helpful, but I still need that perspective from someone who's been there.
