Had a very pleasant experience. Came with passports and 3 passport photos with white background. Filled out the forms given by lady at the reception. She asked to make photocopy of the first page of the passport, and also to send her the entry and exit plane tickets. We had them booked so it was not a problem. I am not sure if it is a rule for everybody. Visa fee is 40$, pick up on the third day, including the day of applying. 50$ is if you want visas next day.
Cheap and easy way to get your Myanmar visa, only takes one day. Staff are friendly and helpful.
