This is one of my favorite places in Phoenix. It reminds me of the coffee houses that I would haunt during my college days. Everyone looks like they think they're doing something super important. Exactly the kind of human being I was in my early 20's.
Of course there's never a seat. And if you were so lucky to snag one, you better hope your conversation is cool enough not to get judged. Mine never are.
Also, come hungry! Pane Bianco is next door, and Lux itself has an AMAZING menu. Their mac and cheese is fire, and don't forget to order a Dutch baby.
