A place quite famous among many for it's Chaat paapri and Dahi bhaalle. But personally I would not recommend it... I guess, we could have found some better option.
Address:- 1396, Main Road Near Central Bank, Opposite Paranthe Wali Gali, Chandni Chowk, New Delhi
Cost:- ₹100 for two people (approx.)
Not something which matches that of Banaras, but quite near to it. You get a whole lot options :- Chocolate pan, fire pan, etc.
