My girlfriend dragged me here recently, so I'm gonna do my best not to rag on Luna simply because it's not really a store for me. In fact, I don't think they sell any men's clothing, so if you're a guy and not being taken here by your significant other, there's no need to check it out. Obviously, I had no say in the matter.
You know what? The Luna experience really wasn't that bad. There was plenty of seating for those who weren't shopping (myself and some other men in similar situations), and the employees were young, female, and cute.
As for the clothes, they have some cool stuff--from nice jeans to fancier/trendier dresses and the like. My girlfriend was definitely a big fan, and she's got really good taste as far as I can tell. Some nice gear here--seems like women from 18-40 could find good stuff here for a night on the town or for work.
