This area is very pricey to eat. But you can still eat well with some research and creativity. You can have a fixed meal for 22 Euros and eat great seafood for 19 Euros. Just take a 15 min train ride to Italy Ventimiglia from Menton or Monaco and get real Italian food at cheaper prices too.
Come join me on this trip. Grab some wine and a baguette and have a picnic with me in some of the most beautiful hill towns and coasts in France (Eze, St Paul, Villefranche, Monaco)
