A stone's throw from Birla Mandir to the right is the much
smaller but quite popular temple devoted to the Goddess Kali. Especially
dear to the Bengali community of Delhi, it is the
centre of celebration during the festival of Durga Puja held every
October. 
Since, Kali is believed to be the manifestation of Durga in her most
terrifying, warlike avatar, liquor is offered to the goddess in this
temple.
The temple is rather small and very simple in design. From within the
temple grows a huge 'peepul' tree that pierces through the ceiling to
shade the temple. Hindus consider the peepul sacred and red threads are
tied around its bark when beseeching a boon.
Timing
The temple remains open in the morning from 4.30am to 12pm and then in
the evening from 4pm to 9pm
