A true neighborhood café, even though it's right in the city center, a rare find these days, with its regulars, its little summer terrace, on a beautiful Nantes square, the one by the cathedral. The service is always delightful. The prices are reasonable. Don't change a thing.
The perfect place to wake up peacefully with an espresso and people-watch. The man behind the bar is super friendly and speaks English. :)
All in all, a relaxed atmosphere.
