Wow that's quite something! I'd love to try it someday, hopefully I'll get the chance. There's a chain in China that does donkey meat sandwiches. They cook buns in a firery hot stone oven and then chop up a chunk of donkey with a glob of fat and stuff it in. Donkey is a tough, chewy and dry meat so they slow cook the meat for a really long time in a flavorful broth and then have to cut it with some fat to moisten it up. It's a bit salty and has a strong flavor and even stronger smell but it's quite delicious.
