The newish (and very nice) Miele Market Kitchen at the St. Lawrence Market offers ongoing cooking classes. They are "one off" classes on specific topics like cooking Thai food, or cooking Indian food, etc., but there might be some of interest to your friend. They cost about $50 to $75 per course, so it would be quite a bit less obligation than some of the more serious courses mentioned above, though I suspect these are more for "fun" than for serious learning.
Bonni Stern's cooking school will have a three week "Back to the Kitchen" course in April-May for $350. The classes are geared toward teaching the basics for people without a lot of kitchen experience and are 3 hours long.
Slightly more advanced, Cirillo's Culinary Academy has a 4-lesson course called "Traditional Culinary Skills" beginning in February. The series costs $ 425.00.
There's a series of 4 basic skills classes at Calphalon. I've heard good things, but it's $500 for the 4 classes, so it depends on the kind of commitment your friend is looking for. http://www.calphalonculinarycenter.com
For a longer commitment, i.e. longer classes and a months-long term, but also more bang for your buck, continuing ed. at George Brown offers an intro course (Culinary Arts I) for $620. This is open to the public, not part of chef training, but obviously a bit more hardcore than your "average" cooking class.
No beginner classes, but Dish on Dupont offers a range of classes (prices, themes, experience are all variable, so you can pick the skills you want to learn). Here's January: http://www.dishcookingstudio.com/zf/e...
I know the GBC one is great, but again, intensive. It really depends how much they want to gain.
