Okay, I want to give this place three and a half stars.
I really wanted to like Lux based on the reviews, but there are things that prevent me from rating it higher.
#1 - I once wondered where all the hipsters roamed in Phoenix. Then I went to Lux and I wondered no more. Pretty much everyone had an apple laptop here. Me and my vaio were the odd ones out. This is just an observation and has not a lot to do with the overall rating.
#2 - It was crazy crowded in the middle of a weekday. The place itself isn't that big, so I assume there's a big following (confirmed by the number of reviews for this place). This made it difficult to lay my things out and have adequate study space.
#3 - Smaller space + people = really narrow walk ways when people are standing in line to order.
#4 - Coffee is good, but not as strong as I personally like.
With that said, the perks here are ambiance (fun art on the walls that I imagine are changed everyone once in awhile), good people watching, parking despite the amount of people here, and the fact that its by the light rail.
So yep, Lux is a solid coffee spot, but I think I'll keep looking for the coffee shop of my dreams.. with table space and stronger coffee.
