For my upcoming trip to Paris, me and my husband are planning to have one heavy meal, be it lunch or dinner, and then head to a nice bar with food for the other meal. So far we are definitely going to Le Mary Celeste. Any other bars we shdn't miss? Vivant Cave vs Septime Cave for example? Not really on our list but Le Dauphin worth the trouble?
I understand too that most of these places do not take reservations. How 'bad' can the crowd get on weekdays vs weekends?
