I lived in Arizona for a couple years recently and just moved back to Iowa, "Salty Seniorita's" in Mesa is Iowa themed, very good breakfast menu named after Iowa players and coaches. Located on Stapley and the "60". I know a lot of Iowa fans go to the "Sand Bar" in Scottsdale as well. O'kelly's is good too, basically all Iowa fans.
Salty Seniorita's is the way to go I think though, it's the Phoenix Iowa Club, lot's of raffle's too. Go Hawks!
