As has been noted elsewhere, fried dill pickles began as a last-ditch effort by a chef to put out food - ANY food - to feed anxious customers at The Hollywood Cafe in Hollywood, Mississippi. From that fated moment, their popularity has spread considerably.
One Athens establishment, The Blind Pig, always has them available. In fact, now I'll have to wander down there and have some in a few minutes, along with my first taste of their Brunswick stew.
My favorite eatery/drinkery, Copper Creek Brewing Co., offers fried pickles from time to time. The chef fried some up one night out of pure boredom; several customers (the regulars first, then others who noted the oddity and HAD to try some) ordered up some until the place ran plumb out of pickles.
Both of these examples use the standard Delta version: sliced pickles cut on the bias and breaded and fried. One nearby restaurant, The Berryman House in Bowman, Georgia, serves fried pickle spears. The people there were indeed amazed when I ordered up some with my breakfast!
Now I can't help but wonder what fried sweet pickle slices would taste like....
