Wow, lived here for 10 years and never knew this was here. In a Quaker building right off the 51 is one of the most Americana events you can catch. Folk music played accoustically, by a varied group of folks.
My son loved it as did my girlfriend. Cheap coffee for $1.00 and sodas, along with homemade baked goods round out the offering. It really isn't a coffee house as much as a great place to hear music.
Very sparse (think Quaker) but a perfect environment for the music. If you need to chill out for a few hours, hit this place up. There are few places in America where you will see this environment. Everyone is welcoming and nice, we will definately return.
