The top diner around has to fit a few criteria. First, it's got to be open 24 hours a day. Second, down here in the South, it's got to have at least a minimum of Southern-fried fare. And finally, a convenient location along a major thoroughfare is preferable. And while it nearly gets the nix for the lack of biscuits 'n' gravy on the menu, Joe's nevertheless fits the bill. Situated just off SE 17th Street, where A1A and Federal Highway merge, Joe's never stops dishing out the grub, whether it be noon or 4 a.m. The breakfast items are suitably greasy, and the lunch stuff is usually served hot and in large portions. And while rumors persist of a secret passageway linking the diner with the School of Culinary Arts with which it shares a wall, the food served here is the sort no chef would claim, lest they be the short-order kind.
