The best restaurant in town acording to me is the french restaurant La Provence.
Its offers the best french cuisine like coq au vin. Foie gras, canard á l'orange and very good franch deserts. Average paid: $30 usd
Ubicated at the entry of Club de golf Cuernavaca close to Cuernavaca center
We higly recommend also Restaurant la Gaia en Cuernavaca Center, with very good modern mexican meals.
More international the famous Las Mañanitas and its less original el Madrigal are still wonderfull places to have a lunch or a dinner.
