There ARE some good butchers, but you will pay BIG bucks for decent beef flesh. They have all kinds of great tuna fish and fish from the Mediterranean, fish ponds, and the Nile. Very tasty and more healthy than loading yourself down with big burgers. I did eat some Kosher Kentucky Fried chicken in Ben Yehuda, in Jerusalem. I even saw a Pizza Hut, but I mostly stuck to more healthy food and ate homemade pizza.
Pizza is very big in Israel.
Also, icecream is enormously popular for kids and all ages, since Israel is so hot most the year. I should not leave out all the good bread I ate. Because you are in a hot climate, your body craves more bread and light food rather than big hunks of flesh, as you crave in the U.S. during the winter. In fact, I found myself frequently just eating two meals a day rather than the three you can easily find yourself eating and getting FAT in the U.S. off of. All the running around, hiking, and swimming you can do in Israel helps keep you slimmer than living in a tropical rain forest like Washington D.C., which rains incessantly.
