The best is Kelly's Ice House for sure! Its an ice cream place, they also offer other foods, such as pancakes, to enjoy. You might want to eat your food sitting on one of the tables outside so you can fully enjoy the beautiful weather!
I took a lovely hiking trip in Corfu this summer!! One of the least admired things about Greece is their hiking, you can find great trails if you do enough research, trust me! This trail is called the Corfu trail
