Java Jive is, in my opinion one of the classic Atlanta breakfast places. I've been there a few times before for breakfast. It's on Ponce de Leon. They have a truly impressive collection of vintage/antique kitchen appliances and dinette sets so the '40s coffee shop vibe is well earned.
I had a pecan waffle and bacon, both of which were very good. They brag about their biscuits so I had to try one. It was truly excellent---moist, flaky, buttery. They don't seem to have any gravy dish to go with it. At the time I was disappointed but upon reflection the lack of gravy helped me enjoy the biscuit more.
