Yeah I know I reviewed them awhile ago, and my conclusion (I believe) was that the sandwich was ok for a change of pace, but not worth getting repeatedly. The fries were ok, because cheese, as The Ancient mentioned. And those little green chopped up "peppers" were actually bell peppers I think, so it isn't quite as ghost peppery as you'd imagine.
It is nice though because if you're lucky you can get them to add the pepper jack cheese to the regular spicy chicken instead of the crappy american I normally have to get. Yes, I'm one of those people that adds cheese to my chicken sandwich, because cheese makes almost everything better, particularly fast food.
EDIT: After reading Crone's review, perhaps I need to try it again. That's the same exact ad they had before, and my Wendy's (which I just went to on Monday) told me it is the exact same sandwich and fries as before, but while it was pretty hot, it definitely wasn't as hot as he's describing.
