I love them ma and pa type of eateries. If you guys are ever in El Dorado they had 2 great mom and pop places:

Double D's Diner and the Edge of Town Cafe...try them out they are excellent.

Also other places I reccommend:

The Cafe in Clay Center, Nebraska (not Kansas) might seat 10 and they have Double Cheeseburgers for a $1.25 when I went.

Also Nebraska has the famous Burger Bar in Wymore which was pretty dang good as well.

Mike, what was that gas stop place we got a meal late at in Council Bluffs, Iowa? That place was a hoot!
