Chili dogs are also popular in areas that have large Mexican-American populations, such as California, Texas and Arizona. In California, regional chains such as Pink's and Original Tommy's specialize in chili dogs and chili burgers. A major difference between chili dogs in the Southwestern United States and Coneys is that Southwestern chili dogs have spicier chili and are served with brown mustard or no mustard at all, whereas Coneys have spicier dogs and are usually served with yellow mustard.
The Texas hot dog, Texas chili dog, Texas hot, or Texas wiener is a hot dog with chili or hot sauce; it is served in various regions of the United States in variations with assorted condiments. The Texas wiener was created in Paterson, New Jersey before 1920 and in Altoona, Pennsylvania by Peter "George" Koufougeorgas in 1918 and originally called Texas Hot Wieners. The "Texas" reference is to the chili sauce used on the dogs, which actually has a stronger Greek cuisine influence due to the ethnicity of the cooks who invented it. It is considered a unique regional hot dog style. From its origins, the invention spread to the Pennsylvania cities of Scranton and Philadelphia. Altoona's original Texas Hot Dogs shop is still open today, having two locations: Downtown Altoona and 58th Street by the Logan Valley Mall.
