I recently read a review of hot dogs. I think it was the Washington Post that rated the various hot dogs. I'm sure you can find it with an online search.

Costco was #1. I don't remember what all they rated the hot dogs on.

My personal guess is that there is not a whole lot of difference in the top 5 or so hot dogs but maybe there actually is, I don't know. Grill 'em up and eat 'em, probably never know any difference.
