Many cities in the Midwest were settled by the French as well.
Visit Wisconsin and tour a cheese factory. What could be more French that sampling several different varieties of cheese? There are even cheese festivals.
There is another town that features a French Square, as well as historic properties where the Marquis de Lafayette once stayed. You might be surprised to learn it's in Gallipolis, Ohio.
Chicago has some world-renowned French cuisine, as well as an Alliance Francaise. It is filled with fountains and statues and street sculpture. In fact, squint a little as you wander through the city, along bridges over the river, and it can almost feel like Paris.
