RE: Indiana to Wyoming
I'd suggest a trip to the Hamburg Inn in Iowa City. You won't be disappointed. They have great pork tenderloin sandwiches, and amazing omelettes. My sister's fave is the Iowa omelette, stuffed with hash browns and cheese. It's a classic, hole in the wall place that employs many students from the U of I. Great service, fun atmospere, and yummy food.
If you're not in a huge hurry, I'd suggest a trip a few miles north of Iowa City to a small town called Solon. Find a place called Joensey's and you're in for the best pork tenderloin sandwich of your life. Also probably the biggest! You can order a half, but it is a fun challenge to eat the whole thing. Simply delicious tavern food.
Also in Iowa City, you can find a great pizza at Pagliai's. Thin crust, not overly crispy, just delicious.
