I'm going to visit some friends in San Diego next week and want to bring them some goodies representative of NY.

Previously, I've brought H&H bagels, cookies from Levain, and cupcakes from Magnolia, but can't think of anything else that's really original. (Once I saw a guy get on the plane with an entire Grimaldi's pizza in its paper wrapping -- only to trip in the aisle and have the pizza slide out after we landed. Sad!)

Any ideas, SE community? The items also need to survive 12 hours in my [unrefrigerated] carryon bag.

Thanks in advance from the happy bellies of those Californians :)
