This is probably the third or fourth time we are visiting this restaurant.  The restaurant is in Tiruvallur and most of the people travelling to Tiruttani or Tirupati usually stop here for breakfast.  If you start by around 6AM in Chennai, you should reach in about an hour and a half, just rite time for a breakfast and coffee 🙂
Ample car parking, good service and a good breakfast is what you can expect here.  Since it is on the highway, weekends usually is very crowded and you may have to wait to get a table if you go during peak hours for breakfast or lunch, other days are a fine.  Definitely recommended for a good decent breakfast on the way to Tiruttani/Tirupati.
