The local Kosher Restaurants are food establishments the majority of diners have never heard of until they realize it is the food of the Jewish people, prepared under strict Jewish dietary laws. Operating under rabbinical supervision, kosher foods require that Jewish laws such as kashrut be observed. Kosher foods must be prepared with laws and regulations concerning food derived from Biblical law. By following these laws, local Jewish Restaurants must be closed during Jewish holidays and Shabbat if owned by a Jewish person. Kosher diners are located in communities where there are large numbers of Jewish people with numerous choices, such as New York City and Toronto, Canada. The popular foods served at local Kosher Restaurants are pizzas and meat dishes filled with Middle East cuisine, bagels, or salads. Fish can be served but not with meat. Kosher Chinese food is common, serving mainly vegetarian, especially on Christmas day. Kosher Restaurants can be found in Israel, such as Kosher Burger Kings, Kosher KFC, Kosher McDonalds, and Kosher Sbarro franchises. In the United States, Kosher Restaurants are less common than in Israel, but Kosher Krispy Kreme, Kosher Dunkin Donuts, and Kosher Subway restaurants have modified menus in order to comply with Jewish dietary law. Baskin Robbins ice cream franchises are kosher in every one of their locations, with signs listing which flavors are not Kosher.
