How far we've come.
It took a while to get some information - had to go all the way to the second page on the name of the owner, Armand Devigne. Some history is here, if you're interested - he had another place called the Chalon Mart.
Recollections from bygone patrons: at a Flickr page that also has the picture.
This page says it was known as a "Family Restaurant" and had the Eiffel Tower on the matchbook.
The online translater says "Chalon" means "Trawl-net." Sounds better if you don't know that.
