Kamla Nagar is one of the more traditional markets in Delhi. I have visited several times and rarely encountered other tourists, especially not group tours. Located in Old Delhi, Kamla Nagar is where the locals shop for everyday goods including bangles, stationery, clothes, and household items. It is also a prime area for mehendi (henna), and the artists sit on stools with picture books of designs. Remember to bargain for all goods and services!
