I've driven by Johnnie's at least 100 times in my like and never seen it open. I thought it had been closed down years ago or was a front for another popular Chicago style business. Last night we were driving by and the lights were on! Obviously we had to stop and find out what had changed. We wre informed that this family business is only open Thursday-Sunday nights. Had I really never driven by during these times? Pizza was true Chicago thin crust. Cut in squares with a sweet sauce that hit the spot. The only thing that could use improvement was the Italian sausage. It was truly a time warp in there as well. Felt like we were back home in Wrigleyville, paper plates and all.
