Mmmmm! In your area, Goldberg's Bagels is yummy and the Ray's on the River brunch is SUPERB -with great views of the Chattahoochee too.
Other faves and their locations:
Pastries A-Go-Go -Downtown Decatur
Thumb's Up -cash only (but ATM instore) -a few locations -we frequent the one on Edgewood in Old 4th Ward
Flying Biscuit -not as good as it used to be when privately owned, but still yummy -several locations -original in Candler Park, one in Midtown, etc.
Crescent Moon -Decatur -fried grits TO DIE FOR
Original Pancake House -one off of Cheshire Bridge and I think there's another somewhere -used to be one in Brookhaven, but it closed.
Ria's Bluebird in Grant Park across from Oakland Cemetery
***All of these are family friendly, but be prepared for long waits at most. Getting there SUPER early -like 7 AM for the breakfast places helps! Call ahead for Ray's on the River.
