Earlier in the day we had a nice darshan of Lord Balaji in Tirumala Tirupati and we were returning to Chennai.  Half-way to home, we were hungry and wanted to have a good vegetarian lunch, my co-brother recommended we go to PS4 Restaurant in Tiruvallur near the collector office. The place was crowded and we had to wait for over 25 minutes before we got a table. The wait was worth though, the food was yummy. If you don’t mind waiting, I will recommend the place. We had bought some snacks and sweets as well, they turned to be crispy…
