　　Over 100 years ago, German immigrants (移民) first started selling hot dogs at places like Coney Island's Nathan's Famous. This is the place where hot dogs were first sold in America, but then something interesting happened. People began making their own hot dogs, and people of every region put its unique things on the snack. So what are America's best hot dogs?

　　On our search for America's best hot dogs, we kept an eye out for places with a unique style of hot dogs. We made sure of considering online reviews from locals as well as the quality of the ingredients (作料). We also considered the entire experience, from driving up to the restaurant or stand to placing your order to taking that first bite.

　　We sorted through dozens of hot dog stands and restaurants in search of the best in America. In order to be included, the vendor needed to have a trademark (商标) dog, with toppings that add something extra. For example, Ben's Chili Bowl in Washington, D. C. doesn't only have a trademark frank (the half­smoke), but it also has a trademark topping (chili). It is thought highly of by locals and professional eaters alike, and eating there is a great experience. For these reasons, it's high on our list.

　　Sadly, there were some famous stands that didn't_make_the_cut. While the original Nathan's Famous in Coney Island might very well be the most well­known hot dog stand in America, it didn't win a place on our best American hot dog list.

　　The stands that serve the best hot dogs are those ancient stands that have been serving the same exact product day in and day out for many years. People usually have to wait in line for one hot dog from such stands.

　　A. learned from each other

　　C. developed their own style of hot dogs
