Java Monkey is in a narrow storefront with a low-key (and very elevated) sign, so it may be easy to miss. But it's been around Decatur for a long time.
This picture pretty much says it all: a warm cup of coffee and a place to relax. The coffee was more of a medium roast, which I prefer. I found the seating to be very comfortable. The crowd is hipster-ish, the bulletin board is filled with concert posters and a smattering of eclectic services.
