Never heard of this sandwich before...

...and I worked on Chicago's South Side for a few years.  Sounds tempting.

"A Gym Shoe starts with a hoagie, Italian roll, sub, or any bread of the sandwich shop’s choosing. That might sound like standard fare, but that’s kind of the point. Standard fare makes up the entire meal; it just happens to harmonize ingredients that most people never think to combine. To do the sandwich justice, the guy behind the deli counter has to create a cultural mashup. He shaves off Greek gyro meat, often lamb, from a rotisserie-style spit. Then he grabs handfuls of roast beef, a meat so English that the French have called Brits les rosbifs since the 18th century, and corned beef, a product of Irish and Jewish immigrant neighborhoods.

The sandwich master piles all three meats onto the bread, sometimes crisping the beef in a hot skillet first. Next come layers of chopped iceberg lettuce, sliced tomato, tzatziki (a Greek yogurt sauce locally called GUY-ro sauce), and, occasionally, mayonnaise and mustard. But it doesn’t end there: Swiss cheese, onions, sweet peppers, and giardiniera (a hot, pickled Italian relish) are all fair game. Customers receive their gargantuan hodgepodge wrapped in aluminum foil and accompanied by a “can pop” (soda) and fries. Those who love sweet barbecue dip ask for “mild sauce” on the side."
