Rajat Singh, another customer, wrote in the feedback book that he was "amazed" by the humble and cooperative staff.
"Since the eatery started service, around 40 to 50 people come here daily," eatery manager Mohammad Asim, dressed in formal white shirt and dark trousers and tie, told IANS.
"I recently got married when I was out on parole. My wife often comes to meet me and I cannot explain the happiness on her face when she sees me working here."
Asim, 36, who has served 13 years in jail, told IANS.
