NDMC proposes to open cafeterias in the other five subways soon.
The proposal to rent out spaces in subways to coffee shops or bakeries by the NDMC in the city's most busy shopping hub was taken up in July.
The cafeteria in the Janpath-Palika Bazar crossing was inaugurated by NDMC chairman Jalaj Srivastava.
It is believed that commercial activity inside the subway would ensure their proper maintenance and people, in particular women would feel confident and safe to use them.
"People should use these subways to cross the otherwise busy roads of Connaught Place," the chairman said.
The subway venture is subject to satisfactory performance in the next three months, he said.
The opening of the cafeteria coincides with the centenary celebrations of the civic agency.
