If a store can have a personality, then What’s on Second? in downtown Birmingham, Alabama, is geeky with a strong dash of uber-cool chic. It’s an antiques shop and a vintage boutique and a collectors’ paradise all in one … and the place where you’re going to come face to face with your childhood. After “Oh, wow, look at this!” the most commonly heard phrase among browsers  is “Oh, wow, I remember having one of those!” What’s on Second? is at 2306 Second Avenue North just a couple doors down from the Urban Standard coffee shop — the two must-go destinations are part of a downtown growth in art, music, food and style. The wooden floors and tin ceilings of the store’s two floors are as much a part of What’s On Second? as the somehow carefully arranged piles and stacks of … well, anything you can think of. There are postcards, books, posters, china, toys, clothes, lamps, household goods, tools, furniture, art work, jewelry, glassware, local history items — and that’s just your first few steps inside the front door. I asked the person behind the cash register once where all this came from — did the owners go to auctions and estate sales all the time? Turns out that most of the inventory comes from people bringing treasures in to sell. Prices seemed a bit high to me, but then I still can’t get used to spending $3.95 for a non-fat dry cappuccino so what do I know? At least it’s free — and fun — to browse and explore and maybe stumble across your own treasure. There’s no Web site, but you can call What’s On Second? at (205) 322-2688 for details.
