they had a sweetheart deal here in Illinois for many years where they were the only restaurant in them over-head oasis things on the high ways.
They were horrible. Bathrooms were nasty, food was nasty, and they knew it, and didn’t care. They were the only exit over the high-way.
But for some reason, I loved Sambo’s and Big Boys (which my wife hated).
Sambo’s had good food. As a kid, I recall the pancakes as “wonderful.”
