You can lose yourself in Puraani Dilli. An entire day, or even a week might not be enough to get a sense of the myriad experiences that await you at every turn. However, if you're pressed for time, a great way to get a snapshot of Old Delhi is on a cycle rickshaw tour. Start early in the morning and spend as much of the day there as possible, give or take a lengthy lunch break at Karim's or any of the other tiny delectable eateries that line the alleys. So, take full advantage of the cold weather and get going!
