3. American and Lafayette are almost the same
Their hot dogs come from the same supplier, Dearborn Sausage Company. Their buns come from the same place, Metropolitan Baking Company in Hamtramck. The key differences lie in the chili and the onions. American’s chili comes from the Detroit Chili Company. Lafayette uses a Keros family recipe “mixed in with a little chili from National Chili Company” according to the book Coney Detroit. Also, American uses sweet Vidalia onions and Lafayette uses Spanish onions.
4. That bitter sibling rivalry you’ve always heard about isn’t all that bitter... or sibling-y
Indeed, Bill and Gust Keros seemed to have butted heads in the 1930s, which gave rise to Lafayette, but Bill Keros sold Lafayette to some of his longstanding employees over 20 years ago. Now it’s sort of a friendly, neighbor-based rivalry (depending on who you talk to). Either way, it makes for great publicity.
