On a normal day, 1 pm is the busiest time for "Tunday Kebabi", the 100-year-old shop that draws people from India and abroad to the crowded Chowk area of Uttar Pradesh's capital Lucknow. Today, 15 of its 20-odd tables were unoccupied. New stickers pasted on every wall inside the shop advertise "chicken and mutton kebabs". The oldest in what is now a chain of shops across Lucknow, Tunday Kebabi has served only buffalo meat kebabs since it started.
