Pretty much any school you pick will be okay, I talked to other travellers who learned in other places and all of them include pad thai and curries. The rest is up to the owner. Atmosphere is funny and good, class size 2-10.
That was THE BEST thing I've done! Guys teach very well and know how to support, especially mentally. I was scared like never to jump but they said a few magic lines and I made it with no problem. It's quite costly, but to be honest all awesome activities cost a bit so if you want it, just do it.
