No website that I could find but they do deliver through some of the food delivery services.

American Joy is a small take out only burger and wings shop on Highland Street just south of Park Avenue just before the curve where Highland turns in Prescott.
I stopped by there a few days on the way home from Memphis and got a burger. They seem to be pretty popular. Several people came in to get order while I was there.
The prices were fairly reasonable and the guy was really nice. It seems that the guy that runs the register also cooks so it took a few minutes to get food but it wasn't all that long.
The burger was pretty good. It wasn't as good as I was expecting but I would definitely go there again.
They don't open until 2 PM apparently but they stay open late, until about 3 AM according to google.
