Raju, I have also seen that movie twice cause i liked it. 

If you are living in kathmandu, and eat momo a lot, then you will get a chance to eat momo made of the same sacrifices that were done in gadimai. I guess you have read the news that the meat was sold to a contractor who is shipping the meat to kathmandu valley.

anyway, people in kathmandu enjoy the momo of all the sacrificed animals in gadimai.....mind your own business. let them follow their tradition.
