The KFC next to them shuts long before they do. The nearest McDonalds (a drive through) is 24/7 but I've been there late at night and it's extremely quiet. Moreover neither sells kebabs, whereas plenty of places which do sell kebabs in this part of the city close earlier.
However, thinking about it more carefully, while I've never bought a kebab from them technically the Chaiiwala which is 24/7 does sell kebabs. They're a bit fancier (and of course, more Indian) than the kebab you'd get from the kebab shop but that's definitely a chicken kebab. Their clientèle in the middle of the night are a mix of "gig workers" and people either going to or coming back from prayers (for whichever of the religions is into praying when other people are in bed - Islam and maybe others?). I have never seen drunk young people in there, but it is open 24/7 so that must happen once in a while.
