What's the difference? Or rather, what do you mean by Chai? As far as I know, that's just a different word for tea. I guess you might mean some drink that has milk?

For what it's worth, I bring in my own leaves to the office.

Specifically, I want Starbucks to being chai tea lattes to china. Unfortunately no one else will join my protests around their beijing headquarters.

Chai is an Indian flavor, I can get something decent at the local Indian restraunts, but that's it.

OK, I was just asking, because Chai is also e.g. the Turkish word for tea. (I guess it's just that some cultures we use the chai-based word for tea instead of the tea-based word use more milk. In Mongolio it's chai as well, and they have lots of milk and butter and salt and pepper.)
