I was in Bangkok on business and had a day to see Bangkok. On recommendation I decided for a biking tour by Recreational Bangkok Biking. It was great, good bikes, a very nice guide and an amazing tour. Through rich and poor residential areas, often nextdoor neighbours, crossing the river twice, 'feeling' the heat, the scents, the food everywhere. Getting lunch at a restaurant which I was unlikely to have spotted myself was the best decision I could have made for my one day tourist experience.
