My husband and I recently returned from a European trip with included a stay in Paris. We arrived via Eurostar and were quoted 75-100 euros as the price to get from the Gare de Nord to Boulevard Montparnasse. This seemed excessive to us so we used the metro.
Returning to the Gare de Nord via taxi we paid 20 euros including tip.
My question is: are there rules in Paris about taxis, taxi queues that are honest/reasonable? If so where are they, especially at Gare de Nord?
Many thanks.
