The condiments are usually a sweet & spicy mango chutney and and a tart and spicy tamarind (imli)chutney. But I think it may be a chili/garlic/shallots chuntney. It depends on the restaurant. You can find these in the Indian aisles of any large supermarket and definitely in all Indian stores. There is quite alot of variety. Traditionally, in India, papad and naan are not eaten with any "dipping" sauces. This is purely an "Americanized" thing. Funny thing is I never get the "dipping" sauces with my papad or naans in any Indian restaurant! They just bring them out as is!
