Thanks "English Tutour" for clearing up the situation. First of all, as far as I understood, Anne is the lady who started this topic two years ago. My name is Jessie and I wish I could get the same reputation as hers someday. Secondly, yes, like "English Tutour" said, the price is not purely for what food cost. It includes lots of preparation in advance and teaching the knowledge and cooking skills side by side. Thirdly, in fact last year in my cooking classes, some new people joined and some quit and some came back later again. It's not like other study that you have to attend constantly, because each class is not strongly related to another and participants bear various objectives, housewives coming for learning local style of cooking for their families, young or single people coming for fun, couples coming for spending time together in a different way. Anyway, no matter the readers' focus is price or whatever, I ask you to read my plan carefully please, trying to get the idea of what I'm doing. Then from there, we could actually talk/discuss. Else, it's just wasting everybody's time.
