I enjoyed this place quite a bit. I recently relocated back to Arizona after living outside of Chicago for the past 10 years. I'm quite familiar with Italian Beef having owned and operated a Chicago Style Eatery for 7 years.
I think Johnny's is an excellent representation of true Chicago Style food. The Italian Beef was excellent and the sweet peppers were done right. The burger? Outstanding, they use the smash and scrape technique ala Shake Shack and it leaves a beautiful crust and flavor on the burger that a char grill just can't replicate. I didn't care for the fries hence leaving off the fifth star but I'd definately recommend this place to anyone for a damn good burger and excellent Italian Beef.
