Begin your trail from Chandni Chowk, where you can treat yourself to delicious parathas, lassi, chaats, and jalebis from some of Delhi&rsquos oldest food joints. From there, if you&rsquove still got an appetite, head to Jama Masjid and the lane that runs opposite to enjoy smoky seekh kebabs, luscious nalli nihaari and mutton quorma with hot sheermal, and delightful shaahi tukda.
