Everytime I make it back, the first place I go is Jonseys. Love those enchiladas. Wife who never been there was suprised that food for 9 people and some drinks was less than 100 bucks, Vegas native.
Knap the original is over in Council Bluffs and that is the one i've gone to for at least 20 years. I was back a month ago and it changed a bit and it's less of a dive bar but still awesome food.
