The "kati roll" is said to have started its life in the Nizam Restaurant in Kolkata, a popular eatery founded in 1932. There are many stories about how exactly the roll got started. Some suggest that hurried office commuters wanted something quick and portable to eat, some mention British babus who were too fastidious to touch the kabab. The most likely origin is probably more mundane, but in any case someone decided to roll things up at some point. Nizam enjoyed a virtual monopoly over this method of serving kababs for decades, but it eventually became commonplace in Kolkata and later spread elsewhere.
