Grotto del Giuvan is a homely nice restaurant at the bottom of Monte Generoso. It has a nice terrace overlooking Mendrisio, but what really distinguishes this restaurant is the use of local produce to deliver excellent food with a genuine touch. Being a "Grotto" (a traditional restaurant in this region of Switzerland), it has a rustic atmosphere.
Among the things we tried out there was the "risotto allo zincarlin" (a type of cheese produced only a few km away in Valle di Muggio) and a delicious entree based on asparagus. The selection of home made deserts was also mouth watering, and I definitely recommend "panna cotta alla farina bona".
