"Former London boxer Gareth Payne lost both his legs in a horrific train accident in the UK seventeen years ago. Today, he battles to make it in Bangkok by selling burgers on the street. 
Photos of Payne grilling meat at his humble burger cart, called “No Name Burgers,” have caught the attention of local media this week. Many Thais honor him as a good example of someone who doesn’t give up."
This is certainly somewhere to visit in Bangkok - have you?
