I have never heard of Yankee Doodle Dandy, but, I have heard of Tastee-Freeze and House of Pies, and definitely Baskin Robbins and DQ.
The last BR I ever remember seein' 'round here was down on 29th and Guadalupe (aka "The Drag") down by the UT campus, but, it closed ages ago.
As far as DQ goes, they're all over the place down here.
And, that Des Plaines McDonald's is the first Ray Kroc franchise. The original restaurant chain started in So Cal.
