Figs is the best antique shop in downtown Phoenix bar none.  I moved into a 1920's studio on 7th ave and McDowell and have been to just about every shop in the area looking for stuff to fill it up with.  Figs is by far the most impressive.  Not only do they have some of the coolest stuff from around the world but the prices are reasonable and the service is awesome.  The guys that work there can go on for hours about the stuff they have in that shop.  I would list some of it myself but I wouldn't even know where to start, just do yourself a favor and check it out on your own, even if you're not planning on buying anything at the moment even a visit is a worthwhile experience.
