Coney Island restaurant Since the owners of the first Coney Island restaurants did not trademark the name or business plan, many other restaurants began using the same name and formula. Coney Islands were opened throughout the city by Greek immigrants. Coney Islands have developed a distinctive dining style that is repeated in hundreds of different restaurants throughout the metropolitan Detroit area and elsewhere in Michigan and other nearby states. There are some regional variations though, such as the chili sauce, which is more liquid in Detroit area Coney Island restaurants compared to the drier sauce served in Coney Island restaurants in the nearby Jackson, Michigan and Flint, Michigan areas. Many Greek diners in Buffalo, New York, and throughout upstate New York, northeastern Pennsylvania (particularly Wilkes-Barre) and New Jersey are similar in format to Detroit-style Coney Islands, even serving their own style of dogs, called a Texas Hot or Texas Wiener. Unlike the Coney Island restaurants in Detroit, though, the Texas Hot is often not the dominant menu item in these establishments. Sioux City, Iowa, also has a handful of Coney Island eateries, as do the Houston, Texas; Oklahoma City, Oklahoma; Scottsdale, Arizona; Tulsa, Oklahoma, and Fort Wayne, Indiana areas.

Leo's Coney Island The Leo's Coney Island chain was created by Greek brothers Peter and Leo Stassinopoulos. The brothers are nephews to Bill and Gust Keros who founded American and Lafayette Coney Islands. Peter and Leo worked at local Coney Island restaurants until they opened their own Coney Island in 1972 called the Southfield Souvlaki Coney Island in Southfield, Michigan. One location opened in 1978 in Michigan and another in 1982 in Farmington Hills. In 1988, the name Leo's Coney Island was given to its newest location in Troy, Michigan. From then on, the chain took on the name Leo's Coney Island. The brothers began franchising in 2005 and are now the largest Coney Island chain in the world.
