Koshy's Calcutta Chaat was started in March 2000 under the Koshy's franchise, at Richmond Road followed by two more branches at Brigade Road
. Sanjay Prasad, who runs this joint, first entered into the business at High Point in Mumbai and has now settled in Bangalore. The place is famous for its Calcutta chaat
-making style which can be sampled in items such as Churmur Chaat (made with channa masala, besan and chutney). During lunch time (12-3), tasty parotas draw in quite a number of customers, while chaats are the main attraction after 4.
