In today's world of fast fashion, it says a lot for an independent boutique to have the longevity of Vintage Martini Consignment. An Observer favorite year after year, the shop again earns a spot on this list for its refusal to keep things static. Owners Ken Weber and Greg Kelly aren't resting on their laurels anytime soon. The duo plans a big expansion a couple of doors down from their current spot with the same mix of contemporary designer and iconic vintage its fans have loved since 1999. But now, you can shop in a bright, open space filled to the brim with art, clothes and accessories.
