I have been to this second cup a number of times, primarily to work and get some things done. Their internet connection is usually pretty stable, and they have some of the most comfortable chairs (the faux leather chairs in the back) I have sat in a coffee shop.
As well, a fair number of plugs for those of us who have laptops with not great battery service.
While there are a number of assorted types that do come in to this coffee place, the management there has been pretty quick to ask them to leave. But with that said, this is one heck of a place for people watching, but can be distracting from the task at hand.
