The Attic is better than I thought, considering the meh reviews. It was recommended to me by a friend of mine with really fantastic taste, so I had to give it a shot despite having seen its Yelp reviews.
It's definitely funky and you should be ready to hunt, because there's tons of stuff. Blessedly, it's pretty well organized into decades and styles. And ohhhhh if only 1940's shoes came in current day size 9!
In terms of price, I found it to be relatively fair. I saw a good amount of stuff that I deemed well priced. However, I asked about a couple of unmarked items and those prices seemed a little high, making me suspicious that they gave me a high price because they knew my interest. And I wasn't in the mood to haggle.
But overall I really enjoyed my trip. And if I lived in Las Vegas, I'd go hunting there regularly for sure.
