I visited this store while vacationing in Vegas. It's tucked away in a strip mall which means it's not huge, but, thankfully, they've arranged the store so that it's still open and inviting--not crammed with so much stuff that you can't move around or shop freely.
I'm bummed that they didn't carry three of my favorites: Noro, Madelinetosh, and Malabrigo, but I did get some lovely Mountain Colors yarn at a 30% discount. Score!
I found the staff to be friendly and helpful, not pushy at all. The staff's friendliness is memorable enough that I'll visit the store again next time I'm in town.
