I just got back from Bali and tried this stuff. The place I went to of course said little about the surely terrible environment the animals are in -- they had a few at the place but they were probably just there for the tourists to see.
Anyway, the coffee isn't anything great. Yet invariably many of the tourists around me were raving about it, I'm sure not in small part due to the focus on it and the high price it demands. It reminds me a lot of the phenomenon of shark fin soup in Asia -- the soup is mediocre at best, but because of its high price people (in my view) pretend to think it tastes incredible.
