Had a great time with them. They provided the paperwork required right away after I paid. As mentioned, the classes did become a bit repetitive because they are actually setup as a place where tourists come to take A CLASS as a thing to do when visiting Bangkok, not a true cooking school. Try to take classes at different times of day to get as great a mix of the recipes as possible.

Note: DTVers could only take classes Mon-Thu when I was attending late last year. Maybe they have more groups, and tourists on the weekends so they want to keep as many slots open for them as possible.
