Took a 101 class at the Wine School in July. The class was actually better than I expected (it was a gift from my wife). Really fun and laid back, which I was not expecting.
The only downside was that a bunch of kids were outside yelling. There is a ice cream store next door (AWFUL, FYI) and these kids were spazzing out on sugar. For the first 10 minutes, they really were annoying.
Other than that, I really had a wonderful time, and will likely go back for another class.
