One of our new favorite things: buying picnic food and bringing it to the beach or a park. This saves a ton of money and is just as fun as eating out! There are a ton of great little markets in Nice walking distance to the beach - perfect. FYI the beaches in Nice are rocky so you might want to buy a straw mat to put your towel over.
My favorite part about Nice were the many (daily!!) outdoor markets carrying food, crafts, art, etc. I loved the markets so much I decided to make my one big Europurchase: a leather satchel handmade by a local husband and wife team. While I was picking out my bag a woman came up to the stand, began gushing about these bags and showed me one she's had for 2 years. She was from England and stopped at this same stand 2 years later for another bag. Score!
