Yangon Visa Run Report:
1) Just get the Myanmar e-visa. Don't go to the embassy. Way too expensive.
2) If you want to go cheap, I would definitely recommend booking Scott Hostel through Agoda. Good location, bargain price compared to prices on the ground.
3) There's like a LOT of decent food in Yangon now--not true 2 years ago--but you really need to be with someone who knows all the good places--probably an NGO worker.
4) Bring a USD $100. The Thai visa office only takes USD, and they have lots of change. Easiest way to break $100 here that I know of. Visa costs $40.
5) No decent, cheap food in the Yangon airport.
Attached is the visa fee table in the Myanmar embassy in Bangkok right now. Now it's neither cheaper nor more convenient to just do an e-visa.
