In 1911, when Delhi Durbar was held for the coronation of the King George V, Haji Karimuddin moved back to Delhi with an innovative idea of opening a Dhaba to cater the people coming from allover India to join the coronation. Haji Karimuddin started the Dhaba selling just two items of AluGosht and Daal served with Rumali Roti.
In 1913, Haji Karimuddin Established the Karim Hotel in GaliKababian, Jama Masjid, Delhi saying, "I want to earn fame and money by serving the royal food to the common man". Allah has 99 names and Karim is one of them. It is because of this very name, Karim is growing day by day.
