Trattoria Casa Colonica is one of the best beach club restaurats to visit in Ischia. The restaurant is located inside the Negombo thermal spa and beach club on a beautiful cove. It’s also close to several of the best hotels in Ischia, including San Montano Resort &  Spa and Mezzatorre Spa & Hotel. Did we mention that Angela Missoni recommended this restaurant to us herself? You know it must be good!
