We were on the Azamara Quest 6 Day Med Cruise last month, and the highlight for both my husband and I was the "Nice Food and Wine Tours". Nadia, the owner and the one women show with her Mary Poppins Bag spent over six hours walking around Nice learning everything and anything about Nice and their Nicoise Cuisine. We book directly through the website: https://www.nicefoodandwinetours.com/.
We had only 6 people on our food tour and we ended up having over 10 different stops, including a sit down restaurant, walk through the market, and multiple stops.
