If you get a chance to watch this, it's an episode not to miss. It's probably the best Iron Chef America I've seen (though I've not seen every one).
There's a giant twist on this one. Chef Fraser leaves his sous chefs at home. He comes into battle by himself. When Symon learns this from Alton Brown, he sends his sous chefs to the sidelines. I won't spoil the ending with saying who won, but it was one of the most "action-packed" episodes I've seen. It was also very tit-for-tat with Fraser and Symon poking at each other during the challenge. Symon appeared to be having a ball -- truly enjoying the battle and the chaos that came with it.
