I have applied for the same program.
I have been to both schools previously (not for culinary though) and though I didn't spend as much time at George Brown as I did Humber, I did feel that GB was the nicer school. The students were just more mature. The entire time I was at Humber it felt like a high school class and was not enjoyable at all for me- and I was only 25. It just had a really 'young' atmosphere to it, and not in a good way. Graffitti, gum stuck to everything, students yelling and swearing and basically it just seemed like no one really wanted to be there. I did have one or two great teachers, but everything else just made it awful for me. If I am going to pay to be there, I don't want it to seem like a public high school, you know?
At George Brown though, the students were much more mature, the school didn't look ratty and worn, the teachers were professional, but friendly. Overall it was just a much better experience. Which is of course why I am choosing to go back without hesitation, where as if it were Humber, I probably would have had to seriously think about it. Just my opinion though, to each their own I guess. It wasn't a really horrible school, but it wouldn't be my choice.
