Nice place! I stopped here on a Saturday around 11 AM. Ordered an Americano and toasted croissant with jam (they also have bagels toasted with cream cheese, oatmeal, and an assortment of baked goods). The Americano was good, though not great. The croissant was absolutely delicious. I took a chocolate chip cookie with me, and it was also great.
The place is beautiful -- very spacious -- but if the weather is agreeable, there is also a cozy, peaceful outdoor patio. I sat outside and brainstormed notes for an hour or two. I think they have WiFi but I'm not sure.
I'd definitely come back if I stay on the South Side again.
