Authentic Thalapakatti Biryani is a must try at Chennai. I visited this outlet at Besant Nagar which is next to T. S Elliot beach. The Mutton Biryani is unique in terms of the mutton balls served which is very crunchy and flavourful. Thalapakatti is a legacy brand. Thalapakatti Biryani outlets are spread across 7 countries across the globe.
