I found Lux on my first trip to Phoenix last fall via Yelp.... and it was definitely a welcomed alternative to the "chain" coffee houses. ... Speaking of which, I am quite partial to the Mocha one such chain serves and so I tried it here. Now I make a point to stop in at least once while I'm in town for Lux's version of it.... ESPECIALLY with the home made whipped cream. Ooooooo. Mmmmmmm. :-p
But seriously, Lux is a great place to go for that cup of "coffee" you're craving, but consider yourself warned as others have mentioned; Lux is almost ALWAYS busy, so seating and even waiting for your order can be rather inconvenient (think Grand Central Station busy on weekends).... and for that my review would have been for 3.5 stars instead of 4.
