i've been there a million times. deep fried dogs are awesome!
when properly done (imo), they're called rippers because the skin tears as they fry.
some people like them just barely fried, called an "in and outer", and some people get them cooked until burnt, called a "cremator".
the only condiment available is their homemade relish. normally, i can't stand relish, but their's is very good. the pictures don't do it justice as it sort of has a neon green-ish yellow color, and just looks cool on the dog.
