Truffle sandwiches.
La Petite Maison Nice

La Petite Maison may attract A-listers, but this restaurant on the French Riviera maintains an almost family feel. It’s ethos ─ “Everyone’s famous here" ─ is literally written on the wall. Enjoy seasonal food to the sound of the long-serving house band in a beautiful dining room with white linens, wrought-iron furniture and wooden floors. If you’re a first-time visitor, try southern French specialities such as pissaladière, stuffed vegetables or courgette flower fritters.
I recommend the truffle sandwiches.
I would highly recommended the canard à l'orange and refuse to eat duck anywhere else. The gâteau au fromage frais is my other go to.
