New Delhi, Nov. 9 -- After more than two months of inactivity due to a bird-flu outbreak, the Delhi zoo reopened its doors to the public on Saturday, pulling in more than 8,000 visitors, including nearly a thousand enthusiastic students from 12 schools. The reopening also introduced a new and convenient ticketing facility - "Insta Ticket Booking Service" - allowing visitors to skip long queues by scanning a QR code at the entrance and securing their tickets instantly. "This made our visit so smooth; we did not have to wait at all," said a delighted visitor, who had come with her two kids, "My kids love visiting the zoo so we come here every winter."
