Bar none, the best coffee shop I have ever been to. The coffee, the bar, the music, the ambiance, all excellent. Truly well done. If you haven't been you should go, bring your creativity, have a coffee and interact with some people.
(This is coming from a guy who grew up in Seattle and has had coffee at Cafe Greco. However in fairness, the deserts are not even close to what Cafe Greco has..... they would have to be seriously earth shattering to be better in that department.)
Don't let that detract you. Go to Lux. It's spot on.
