I trust this is allowed on here.
Whilst we were in Bagan we had a very helpful local driver who was more than happy for us to repost his details here . His name is Mr Bu and his mobile number is 204-2311. His rates were very competitive, he speaks excellent English, seems to know just about everyone, and was very friendly and flexible on arrangements.
He took us on a couple of tours including a half day trip to Mount Popa. Fully recommended.
