Cultural Immersion

I am doing a class/presentation/module on cultural immersion for a visiting Executive MBA class from the U.S.  Basically, I am trying to un-package India for them and it is a fascinating exercise.  What do you focus on? Values, food, music, bargaining? There are many good books on Indian culture including A.L. Basham and India Unveiled.  Been reading a lot.  Have about ten slide presentations and will probably show them about five in the three hours that I have.  Also doing interactive stuff.
