Head out to 100A Garpar Road which was home to Sukumar Ray, his father Upendra Kishore Roy Chowdhury and son Satyajit Ray. Sondesh was published from the ground floor here. Sukumar Ray would hold many literary and cultural meet-ups at this place (Rabindranath Tagore was one of the regular participants). The building also houses the Athenium Institution Higher Secondary School - you must check out Satyajit Ray's autobiographical narrative of his childhoos, Jokhon Chhoto Chhilam, for a description of the institute.
