Lux is SO bi-polar. Half the time the music is unbearable- industrial and LOUD and the service is little more than a grunt from the guy taking your order and your money. The other half of the time the music is Jazz and very conducive to drinking coffee and talking and seemingly more appropriate for the environment. Every once in a while there will be a semi-friendly face at the register, but not very often, in fact it is rare- I once made the mistake of ordering a small drink and they snarled at me that they \"only pull double shots\" which I had read only moments earlier on the menu but had already forgotten (mommy brain) but they definitely could have handled that a little more nicely. They have books and other kid entertainment so I know they WANT to be kid friendly but the loud industrial music has got to go. The coffee is good and the environment is cool. The pastries are heavenly. I would have only given them 2 stars but the owners are pretty cool and I have hope that they will become more consistent with the music and service. I haven't been there in  a while, mainly for fear of a bad experience but I will give it another chance. I hope they become less focused on being \"cool\" and more focused on giving customers a genuinely well rounded- good experience.
