"One of the world's most unusual stores." That's their slogan, and yeah, it's pretty accurate. The variety is mind-boggling... rugs, mirrors, paintings, handmade furniture, dishes, sculptures/statues, farm equipment, and, as other reviewers said - junk. Prices seem reasonable, I guess - kind of hard to know if $600 is a steal or a rip-off for a life-size flying unicorn (see pics)... I mean, I'm not sure where I'd go to compare prices on something like that.
I wasn't looking for anything in particular, and that's the right attitude for this place - you never know what you're going to find. Thankfully I followed Eugene's advice and only took in the cash I was willing to spend - otherwise, in addition to the neat little end table / magazine rack I found, I definitely would have walked out with a super cool but totally unnecessary $200 iron monkey statue (see pics).
One last note - it's a big place, and a good portion of it is pretty much outdoors (some covered, but not air conditioned), so if you go during the summer months, I recommend going early, before it gets too hot - they open at 10am (7 days a week). Otherwise you won't be able to really spend the time this place deserves.
