As you may know, we'll be in the Bay Area in June for the Great American Food & Music Fest.

Which got me thinking: What can I get in San Francisco/Bay Area that I can't get anywhere else?

I'm talking about regional products and foods that you've never seen anywhere else. For example, the It's It ice cream sandwiches.

There's gotta be other stuff I should put on my to eat list.

I'd also be open to restaurants doing something you've never seen anywhere else. (For example, if someone were doing a really cool/unique-to-SF pizza style, that would count, but merely saying I have to try, say, Pizzaiolo, wouldn't—because I can get Neapolitan-style pizza in any number of places.)

Anyone have any suggestions?
