Normally, you would be correct, but unfortunately this is an exception to the rule that a singular proper noun does not require an article. The correct sentence is:

"He's learning French at the French Cultural Institute."

Other exceptions include: "the Colorado River", "the Statue of Liberty" and "the Eiffel Tower".
