Wendell Trogdon wrote 17 books! Interesting. Mainstreet Diners didn’t show up when I checked Amazon.com because I was looking for Cafe Indiana and those words and somehow Duffy’s book was included. I searched inside Mainstreet Diners in Amazon and pork tenderloin sandwich came up only once. That was a surprise. Also no mention of the oldest mainstreet cafe of all, Nick’s Kitchen. The book is 7 years old. Would that be considered dated as far as restaurants go? I noticed that in Cafe Indiana several restaurants reviewed already had a slanted semi-transparent overprint of "CLOSED" over the review and the book just came out.
