For "little balls of greasy heaven" I recommend to anyone who passes through Atlanta that they stop in at The Varsity on North Avenue. It's downtown and just off the Georgia Tech campus. Order a couple of chili cheese steaks (that's what they call the burgers there), some onion rings, a Coke, and extra onions (hand-diced and you get Vidalias when they're in season) to go on the burgers. The burgers, dogs, fries, and rings aren't the same since they stopped cooking them in honest-to-god grease (it is a pisser, ain't it grampster?) but they're still good eats.
Come to think of it, I haven't heard "What'll Ya Have!?" in a while...and Miss Priss is off work tomorrow today...she likes the food there too...I see a Varsity date for us in the very, very, near future.
