My favorite stores in the mall in the 80s and early 90s were the Electronics Boutique, Waldenbooks, Tape World or Sam Goody, and Sharper Image. None of those thing exist anymore. When I go to the mall now, it's 90% clothes and jewelry, and I'm just not that interested in it.
My kids like the rock/skate shops like B&C, Hot Topic, Zumiez, Vans... but it's still just basically clothes.
