I mentioned I was going to be traveling south and would stop at...
Lem's Bar-B-Q311 E 75th St, Chicago
... and inquire about the “Fry Sandwich”.
I also ordered a Tip and Link Combo
After asking for a Fry Sandwich they said...
The tips come with fries, you have to put it together yourself. We’ll give you some extra bread and put it on top.
They knew what I was talking about.
I figure it is something like dipping your french fries in your Frosty.
About what you’d expect, fries on bread. Nothing transcendent.
