I used to own a coffee shop in a good sizd city where there were many coffee machine service options. Does anyone have any suggestions on possibilities in Khon Ken, Roi Et, or Maha Sarakham?

There is a shop that repairs commercial-type espresso machines and sells related supplies on the soi that runs behind the main post office in Khon Kaen. It is the branch of a Bangkok operation. I'll get more details over the next few days when I go to the post office.

This is the website -- it does not mention the Khon Kaen location but I just went by there this AM. I get the feeling looking at the repair shop that they ship their repairs up to KK as there just seems to be too many commercial size machines for this area. Again behind the post office

We are in Surin and purchased our machines from Bon Cafe in BKK, but our service centre and supplies come their

Office in Korat , I order supplies from our cute young rep via LINE. And receive the next day. She drops in a couple of times a year.
