Zia reminds me of High Fidelity, in a good way. People say Las Vegas is a wasteland of Walmarts, smokers, hookers, and high school dropouts--which is sorta true. But Zia gives me hope that I could at least buy some great vinyls and used cds at very affordable prices. They have most genres covered, from Lady Gaga to Slayer to Weezer. Listening stations are scattered around to hear recommend bands and singers. They also have dvds and weird-ass novelty items. Get the Zia card (if they still have it), accumulate points to earn discounts on your next purchases.
So next time you feel like doing something un-Vegas and more Portland, head over here. While you're at it, go to Buffalo Exchange to get some somewhat overpriced used clothing to feel extra indie hipster.
