I have been to Ann Sather's Andersonville location a handful of times and have never been disappointed. The eatery has some of the biggest serving sizes I have ever seen.
I usually get an omelet that includes spinach; quite good. But the last time I was here I ordered the Jamaican Jerk Scramble, which is simply amazing. It includes chicken, tomato, onions and a tangy jerk sauce, and the consistency of the omelet is just right: not too runny, not too dry. But it is so big, I can't finish it, which is saying something for me.
You get two sides with your omelets -- including biscuits and potatoes -- but one of them must be the cinnamon rolls. You get two per order and they are absolutely fantastic. Save one for later if you can't finish it all.
Ann Sather is perfect for brunch. And the Andersonville neighborhood itself is a really fun to place to walk around. You should stop off at The Brown Elephant and find a bunch of bargains on used goods.
