I coordinate dinners for Ex-Chicagoans in DFW, monthly, at various Chicago owned and Chicago food restaurants in the DFW Metro-plex. We are also on Facebook. There are quite a few places to get your fix.
I like the Chicago Corner and Danny’s Pizza in Arlington, Chicago street and Rosati’s in McKinney Bel Gusto's in Irving is from New Berlin, WI. I meet Ex-Chicagoans at least once a week or two. we have around 324 members but only 20 – 30 people will come out for meetups. We have a email listing of all the places we have found in the Metroplex called "Ties to Home"
