I wrote a book at Coffeeworks, or at least a good chunk of one. It's a great place to hang out and work. I usually hang out here on Saturdays before a standing 6:00 date, so I know the place well.
Sometimes, there are lots of angsty, purple-haired teens hanging around the place, and occasionally there have been old farty-types arguing loudly about politics...but other than the sometimes unpleasant noise, it tends to be a pretty laid-back shop.
Their smoothies are delicious, and the coffee is good. I agree with Garrett G that the chocolate coffee beans are indeed delicious and sickening. The music is just loud enough to hear, but not so loud that you can't think.
They have a decent selection of things to eat. It's not a place for lunch or anything, but they have the standard coffee-shop style foods you'd expect...biscotti (Try the grasshopper mint!) and muffins and scones and other pastries.
