many, if not most malls got into kind of a chain copypasted slop racket in the us, where you could expect to see the same couple dozen stores in different malls across the country. if you've seen one you've seen 'em all basically. oh wow it's another forever 21 and claire's and sunglass hut and apple store and a sbarro's and a cinnabon, amazing. the unique-to-that-mall quirky specialty stores often just don't survive anymore in an age where amazon and ebay invalidate the notion of something uncommon/rare being physically hard to come across if it's not in your immediate vicinity. even though, those are the coolest stores with the most knowledgable people.
