There are not many reviews that I could find about Mr. Oat so I wanted to leave my opinion. We used Mr. Oat two weeks ago while we were in Bangkok for two 1/2 day tours. One around Bangkok including: Grand Palace, Reclining Buddha and Emerald Buddha and the other to the train market and floating market. Both tours were great and Mr.Oat was a very informative and attentive guide. He used to teach history and told us a lot of interesting facts and background about the sights. He introduced us to many new foods and helped us orient to the city and Thai culture. The driver was also very kind and always had cold water waiting for us when we got in the car. Overall a good experience and my husband and I would definitely recommend.
