The main difference between Resto and a restaurant is that Resto offers a more casual dining experience, while restaurants are typically more formal.  Resto also offers a smaller menu with fewer choices than most restaurants. It derives from the French word "restauration," meaning "the act of restoring." A restaurant is a business that provides food and drinks services to the public. A Resto is a specific restaurant genre characterized by fine dining, an intimate setting, and often high prices.  However, both Resto and restaurants offer fresh, made-to-order food.
