I actually got to try this, and I'll give all who want to try it a word of advice.
If you aren't staying in to eat, order a large drink. Otherwise, make sure to ask for a refill. Trust me when I say, you'll need it.
This thing is SPICY. It's one of the spiciest sandwiches I've ever had. In fact, I'd dare say that it's spicier than what Wendy's has to offer, and that's pretty spicy.
One complaint I've heard is that it's so spicy, that you can't taste the chicken itself. However, I beg to differ. I guess it requires you to be used to having spicy food, such as I am. As far as spicy foods go, it tastes pretty good and is a real contender with fast food joints.
I do recommend it, but it's best to take caution. Get that large drink or you will regret it.
