I've lived in California my entire life and I ain't never heard of a fucking "Mission burrito." The picture looks like some Tex Mex burrito with the corn in it. Our thing is usually just putting avocado in it. Not to mention the entire state used to be part of Mexico, so if we are gonna be known for burritos, it's gonna be the authentic Mexican kind.
There is also no such thing as "California clam chowder." San Francisco is well known for chowder bowls because they make really good sourdough in San Francisco which they make into bowls and serve New England clam chowder from. I make a point of getting one every time I'm in the city. Absolute best shit.
Who made this chart? I can't trust anything on it since the things for my own state are either totally wrong or at least slightly off from reality.
