You can take a delhi darshan bus which starts from red fort in morning and takes you to all tourist places in delhi and leaves you back at red fort. Then you can have dinner at Haldiram's chandni chowk
Thanks for the lovely 15 suggestions. Ended up eating breakfast from Saravana Bhawan (South Indian)from CP then went to Jantar Mantar and Ugrasen ki Baoli . Then in afternoon roamed around CP and Janpath market, then in evening had drinks and snacks from Warehouse Cafe (CP) which was below average. Not recommended at all.
Then went to India Gate at sunset , then to Bangla Sahib. Now back at my hotel.
If you read till here. Thanks.
