This restaurant chain is one of my favorite Chinese restaurants. This one in particular is the oldest. Even though I haven't been to this particular restaurant. I've been to the ones in Anna Nagar and Indra Nagar and I can tell you that the quality of food is simply superb, authentic and consistent across all outlets. The ambiance and quality of service is also good.
Although its a little expensive, its worth it. If you are looking for something inexpensive yet authentic, try The Cascade in T Nagar or Kader Nawaz Khan Road, Nungambakkam.
