Lux is the place in Phoenix (I prefer Cartel in Tempe).\nTheir espresso is excellent, and the majority of their baristas really know how to work it.  Most of them are super nice, too (most notably the very cute Jane who may or may not still work there).  \n\nMarked off a star because of the occasional totally indifferent barista (one of the guys in particular, though I refuse to name names), as well as the annoying client\u00e8le.  I have attempted to start conversations with fellow customers here, but they just are not having it.  I've decided that I just don't want to spend time in such an unfriendly place, even if the baristas ARE fantastic and cute.
