There's a jillion cuisines out there, but LJ only gives you a limited amount of options, so 'Other' is there for you to check off if you want to add those not on the list. I threw together a bunch that I'm familiar with. :)
1) Traditional 'typical' foods like hot dogs and hamburgers, etc.
2) Regional dishes like New England clam chowder and Southern fried chicken, etc.
3) 'Early American'-type dishes, usually served in Colonial-themed restaurants: Yankee Pot Roast, corn fritters, apple cobbler, etc.
Admittedly, I don't know all the varieties, though I do think of poutine, French fries with vinegar, and Prince Edward Island potatoes when I think of Canadian cuisine. I'm sure my Canadian flisters can give us a bunch more. :)
