Guess where he was eating?

Just got this note from an Ohio man, who needs someone with a more encyclopedic knowledge of the Denver dining scene than I possess:

"My wife and I will be there the weekend of February 6. As a kid I'm pretty sure we drove through Denver on our way back from California and I seem to remember a restaurant called the Print Shop, or something, it had a newspaper theme. They had this amazing pea soup. Isn't that strange... This would have been 1973. I can't find anything on line... is there any chance this place is still around?"

Can anyone guess where he was eating? No DINR deck award for the right answer -- just the warm feeling of having helped a fellow gastronaut.
