Do you want to learn Hindi?
roundsquare: I'm of Indian decent but only speak English.  I would like to.Also, as a side note:Even though you can totally get by speaking EnglishI'm living in Chennai now and make a few trips to Mumbai for work.  In Chennai, I've had few problems with English, but in Mumbai, it can be quite a bit harder.  If you stick to touristy things English is fine.  But if you want to try traveling by auto-rickshaw or talking to locals, you will run into difficulties without Hindi.
