restaurants in Chennai

I have recently shifted to chennai, and initially whenever we went out I loved south indian fare at Sarvana or Sangeetha , but then I longed to eat north indian food, and here so far I have been unable to find a good north Indian restaurant, either there are five star restaurants far too expensive or road side type. There was a big hype about this restaurant-EDEN in Besant nagar, so we went there, ambiencewise its just ok but food and service is not even Ok. In this respect Hyderabad is completely cosmo and much more happening.
Here even Saravana doesnt have very good ambience, comparatively sarvana in CP Delhi is fabulous.
