Are there any dishes that are indisputably from a specific place in your country?

Yeah. There are many dishes whose origins are up for debate, such as arepas and tamales, but what about ones that are undeniably from a specific place?

For example, here in Mexico, nachos were first made by a guy in Piedras Negras, Coahuila for some American tourists, the Caesar salad was made in a restaurant in Tijuana owned by an Italian immigrant, and tortas ahogadas are from Guadalajara... mostly because no one else likes them.

Name the place where the dish is from. Don't just list nationally popular food.
