It's been quite a few years...but my mom took my sister and I to one that was held at one of our local high schools. I'm thinking it was something like the Betty Crocker cooking school or show.... or maybe it was put on by some product...sorry I can't remember.
We really enjoyed it and took lots of notes/tips. They had some great displays and some freebies and also some taster-tables of what they had made. We had a great time.
