Completely off-topic here, but the coffee house mentioned in this Engine Yard article (Intelligentsia) is really the best coffee in Chicago--if not the US.

Also, there is no way that Groupon needs a data center--how can they be spending millions on hosting each month? Something doesn't add up...

Intelligentsia's pretty good, but they're going to have to arm-wrestle Ritual for the title "best in the US". ;)

Coffee comment seconded.

About to pull a few shots of Black Cat right now...

Engineyard + support is pretty expensive.
