Let's Talk Hot Dogs - Regional Styles

I recently re-visited my old NC State stomping grounds and stopped in at Cloos' Coney Island Hot Dogs. I like to go with a place's strengths, so I had the classic Detroit style Coney Dog.

I was in Holly Springs a few weeks ago and had an authentic Sabrett's hot dog (with Sabrett's toppings) from Frankie Frankk's Hot Dog Cart (which has moved from downtown to a farm somewhere off Avent Ferry, still in Holly Springs, I have to go find it again), a solid New York City Dog.

So, my question fellow Triangle residents, where to I get the best of each regional style hot dog? Who has the best North Carolina style (is it The Roast Grill on West St in Raleigh? I keep hearing about it but haven't been in), is there a Seattle style (cream cheese and onions), Chicago style, other styles I don't know about?

Help me, hive mind!
