Another NRI hehehehe you'll be surprised Vongali VOVu, there are more places to eat north indian food in tamil nadu than there are food joints in west bengal...having lived there for 3 years, though born and brought up in hyderabad, I can tell you this.
So surely vongali vovu who doesn't even know the difference between b phor bhombhay and b phor bhaijhag doesn't really have a voice to comment upon idly sambar or dahi wada...
