In Jacksonville, depending on when you hit the city…(Bk or L) stop at Blue Boy Sandwich Shoppe right off I-95. You can get the address. I’m too lazy to look it up. This place is a great roadfood stop. You may have to wait in line a few minutes, but while you do you can watch the show. One grill guy handling lots and lots of orders…Pretty amazing stuff to watch. Good sandwiches made on special Egg Bread..Huge, good and reasonable. Try the hot pepper mash on your sandwich, too.
I’ll edit this for you with a few more places shortly.
