Monreale is a beautiful cathedral know for its mosaics. The area around the cathedral is known for its touristy stores and stalls. The one exception is Elisa Messina who sells beautiful ceramics, especially nativity scenes. In true Italian fashion her nativity scenes include everyone in the village including sheep and goats and not just the manager, Jesus, Mary and Joseph. She also has a selection of plates and pitchers decorated with grapes and leaves. And just in case you have been wanting one, you an also buy baptismal fonts. The store is located near the cathedral. This more art than crafts and she has shown her work all over the world.
The Trappitu has all types of seafood dishes, but the terrace is the reason to go there. Ask what is fresh for the day and you won't be disappointed. I had fried calamari, which is nothing like the heavy dish you find in the US. It was wonderful. You can sit outside and enjoy your meal while you enjoy the view of the rocky shore. You will need to make a reservation well in advance for a table on the terrace. The building is a converted oil mill so the structure is interesting. Pizza is also offered if you have had your fill of seafood on your trip around Sicily. The restaurant is actually very large, but like I said if you want to sit on the terrace call ahead.
The Gelateria Pasticceria Recupero is the best ice cream shop in Palermo. I try gelato in just about every city I visit in Italy and this is among the best. There are warnings everywhere to be careful that some of the gelato is made from mixes and is not considered authentic by Italian standards. I have no idea whether this is authentic gelato or not, all I know is that it is good. They have a lot of different flavors to choose from including some that are pretty unique. They also sell other bakery items that looked like they would be good.
