In all the old towns you may buy the most lovely stuff, fragrances, soaps, lavender to put between your linen, beautiful, region-specific texitiles, ceramics. And of course go to one of the many, many restaurants and taste the good things of the region: socca, gnocchi, olives. And Menton
is the town of the lemons!
