Near Juma Masjid,
If you are a frequent visitor of Thattukadas then I would recommend one of the oldest and most popular eatery at Kesavadasapuram run and owned by Habeeb Ikka.
The shop opens by late evening, there are no sign-boards as such but could locate the shop by the crowd gathered around the place. It's one of the best Nadan Food spots where people mostly opt for a take-away.
They provide varieties of Chicken fry, Beef roast, Chilly chicken, Beef fry, Porotta, Appam, Idiappam, Puttu, Kappa etc...
