Can someone please recommend great web links about Chennai?

Even personal but knowledgable opinion will do.

Specifically, I am interested in knowing

1. Indoor (preferably airconditioned) and outdoor places for sight seeing

2. Rankings and reviews for restaurants, or must visit restaurants (non-veg included)

3. Things unique to Chennai
