There's some pretty good chow in France and it's not all snails and smashed up livers. Let's grab a sandwich at a sandwich shop, tack on a nice chunk of flan, throw in a 3 euro bottle of wine, and settle into a nice scenic spot for a lovely little picnic.
Hit the city market, snag some fruits, cheese (lots of good cheeses in France), olives de Provence, and of course a baguette, and you're ready for whatever Nice can throw at you.
