G.T. South's in Indianapolis has the best pulled-pork sandwiches. And very inexpensive, too.
When i lived in Chicago, many places serving the Vienna Beef hot dogs were my favorite.
But, I am on the hunt for the best (pork) tenderloin sandwiches. It's an Indiana thing, to look for better ones.
When in college, I also liked some female-companionship-sandwiches...bone in, and buttered buns.
