We had a look into various points of PBP interest in 2011. https://www.youtube.com/watch?v=DKvmeb5XVvUOut of the various points the most interesting weren't directly linked to PBP. Point Zero is next to Notre Dame, and the Au Pied de Cochon is a brasserie with a pork-based menu. https://www.pieddecochon.com/en/ as it's open 24 hours it's a handy point for validation.
