Tamil Nadu provides visitors with a wide variety of delicious food both for the vegetarians as well as the non-vegetarians, though most food in Tamil Nadu consists of grains, lentils, rice and vegetables. Spices are added to give a distinctive taste. Rice is the staple diet of the state. Idly, Dosa, Vada, Upma, Sambar, Rasam and Coconut chutney are the other common delicacies. Chettinad cuisine is a specialty in Tamil Nadu and is a delight for those who like hot and spicy non-vegetarian food. This type of food has several variations of fish, mutton, and chicken dishes of which the Chettinad Pepper Chicken is a specialty. The Tamil style of Mughlai food can be savoured in the Biryani and 'Paya' (a kind of spiced trotter broth eaten with either Parantha or 'Appam' (a type of Dosa)). Tamil Nadu, especially Chennai, is famous for its filter coffee, as most Tamils do not prefer instant coffee.
