Thanks Geo Tiger Ji, much appreciated.
I'll be there just under a week, so I don't think I can participate in festival activities. I heard Boulder is bit expensive. It looks like it's just like anywhere in the US where our fellow people are working in similar jobs. Good to know.
Gooling gives me these options with regards to Nepali food.

Little Nepal (Colorado Spring)

It would be nice to know which has a tastier food., probably missing some other locations???
