Theni district has a food culture that rewards anyone willing to look past the obvious. The towns along the Periyakulam—Cumbum road each have their own long-standing kitchens, and the competition between them has kept standards high for decades.
Hotel Thattivilas has been part of that landscape since 1975, with branches serving Theni and Chinnamanur. Being one of several respected names in the district is not a weakness — it is why the cooking here has never been allowed to drift.
If you are passing through, the district is worth eating your way across slowly. We would simply suggest starting with the kulambu.
