When I was in Grasse during the summer, I strolled around town looking for a good looking, affordable restaurant at lunchtime. In the end, I opted for the crepe restaurant Le 9 in the Place aux Aires, because it had a nice terrace and a menu for € 12.50. The menu included a main, dessert and drink. The service was good at all times, they were to explain each dish (my French is pretty basic), and the food was pretty good. I ate chicken with gravy, potatoes and salad, and for dessert, a delicious chocolate crêpe. I was quite happy, so I recommend it.
