The above linked article has a list of the best sandwiches in every state. I started looking through the list. My favorites, judging by description and some photos are the housemade mozzarella in Arizona, the Reuben in Michigan and in Indianapolis, and a few of the fish sandwiches would be appealing.
I think the hot brown sandwich in Kentucky is a little overkill. The lobster roll in Maine looks good, but the dungeness crab rolls in San Francisco are much better, I’m sure.
The Pho dip sandwich in Oregon looks really good. I was surprised that the Pennsylvania one was not the Philly cheesesteak.
I was disappointed that the California one is in Southern California. It looks delicious, though.
