I don't recall searching for anything in Chiang Mai on You Tube, but this was in my suggested viewing list. So I watched it & here it is you're interested. Be aware it says that it was uploaded 10 months ago so costs may be dated. I also notice that at one point he has a bottle of water but it wasn't added to his total cost (IIRC)
My own costs in Khon Kaen yesterday were 156baht
Breakfast (2 banana cupcakes)11B
Coffee 35B
Lunch (Kai Geo Moo Saap) 35B
Tea (Panang Gai) 35B
Coke & Water 40B (was out walking & spotted the Norwich v City game at 2-0 so decided to stop at the bar & see the other goals. This is not typical of my daily spend - but then again only 40B)
