I personally didn't like Teppanyaki at all, and won't go back. The food wasn't bad, just bland, boring, and overpriced. The chef didn't put on any special show, and we have better teppan dining closer to home.
I love the Candlelight Processional, though, and we always do the package. Le Cellier is my favorite Disney restaurant, I highly recommend it as well.
One tip is to sit a bit further back during the processional, you get the whole presentation instead of just seeing the front row.
