@ Nick. I went to a place in Oceanside called Philly's best. They used those rolls shipped from Philly.
Almost nothing is exclusive to anywhere these days. You can find authentic restaurants here for just about every type of food, country etc. just as it would be made in the originating county.
I still doubt you'll find a place that makes vegemite sandwiches and fairy bread. :troll2:
Also, I've been told that you can't actually bring vegemite into America because of the sodium levels... I don't know if that's true, but its definitely a weird reason.
