I look forward to eating a specialty dish from every place I visit. A dish of Saint Peter's fish is popular among tourists partly because it is said to be blessed. Slits are made on the sides of the fish, and it is fried. With a squeeze of a lemon on it, you eat the fried fish while it is hot.
The fish, a type of tilapia indigenous to tropical Africa, are believed to have reached the Sea of Galilee in some way, around the time the lake was formed about 20,000 years ago. That’s why the fish in the winter time are densely gathered mainly in the northwestern part of the lake, where there are warm water springs. Someone, somewhere decided this fish will be associated with St Peter (I know he was a fisherman, but we don't know what he caught, except for "fish"). For that matter it is not impossible that the tilapia in Africa originated from the Sea of Galilee.
The fish served at lakeside restaurants aremot likely not caught in the Sea of Galilee. Most of them are farmed at 'kibbutzim' in the Golan Heights and other places. Those caught in Galilee apparently don't look so good and are likely to be small fare.
The beer is a Maccabee Premium Lager. Quite nice.
