Traditional Sicilian food

Wanting to try more local food, a friend took me to a traditional food place. It is not a fancy restaurant; instead, it looks like a “Fast-food” place. All food is precooked displaced behind glass window. You can order a combo with 4 items (1 meat) or 6 items (2 meats). With a history of poor people food, I do not judge food on where or how they are served. But unfortunately, because those places are selling for cheap food, so the quality is not that good. I picked everything traditional, just like my friend said: everything here is traditional. Unfortunately nothing is done especially amazing. They grilled the meat after we made order, but their quality not very good. Although at lunch hour, it was packed with people.
