Hello, I'm traveling alone to Paris in mid-January and realize most of the restaurants I'd like to make reservations at only accept reservations via phone. My french isn't all that great, so I'm thinking it might make more sense to wing it and show up at a decent hour when the restaurants are likely not busy. I'm specifically looking to make reservations at: Clown Bar, Josephine Chez Dumonet and Caviar Kaspia. Do you think this is ok? Or should I still try to make reservations for one person via phone?
