A trip to Kerala is never complete without a traditional sadhya, that is served on a banana leaf. Kochi's BTH (Bharat Tourist Home) has a restaurant which offers the traditional sadhya on Sundays for guests. Naturally, people flock to this restaurant on Sundays to enjoy the traditonal meal which is priced very reasonably.
Despite the long queue of families and the noisy canteen atmosphere, a visit to BTH is worth it if you are visiting Kochi.
