I had the "El Jefe" wings here last night. As a spicy food connoisseur, I believe that these wings are by far the hottest food I have ever tried to eat. They are definitely worse than the famous habanero poppers at Salvador Molly's. I recommend the "Very Hot" if you want flavor.

Fire on the Mountain has the best wings in Portland, bar none. The traditional sauce is of course excellent, but they have a variety of other sauces to choose from as well, including a very tasty spicy peanut sauce.
