Nick is fantastic!
I haven't taken a baking class with him, but I had lunch with him in NYC. A wonderful friend of mine had done some food styling for him, and when we were in the city, she called Nick. He graciously agreed to meet us for lunch, and it was just fantabulous.
He is so down to earth, has a super, dry sense of humor, and tells great stories.
He's also fun to wander the ethnic markets with...
I canjust imagine how wonderful his classes are.
Another great baker who teaches well and has much to share with students is Peter Reinhart. If you have a chance, take one of his classes.
