The 10 Best Cheap Eats in Chicago
"It’s with good reason that Portillo’s has long been a cheap-eats staple in Chicago; the beloved Chicago-style hotdogs are no more than $4 and piled high with mustard, relish, celery salt, chopped onions, tomatoes, a kosher pickle and sport peppers. The rest of the fast-food-centric menu is just as wallet-friendly, peppered with the likes of a char-broiled chicken sandwich ($5.29), an Italian beef sandwich ($6.29), crinkle-cut fries ($2.69) and a chocolate cake shake ($4.29), which is actually blitzed with ice cream and a slice of chocolate cake."
