But the intent gaze of her kohl-rimmed eyes, as she stands with arms folded on the edge of the dance floor in an all-black outfit, watching couples bob and twirl to the music, gives away her real occupation.
She is Social's famous female bouncer.
Now Mehrunnisha is expert in breaking up bar fights, frisking female customers, and uncovering illegal drugs.
"She was fierce and determined, and the rest is history."
The 30-year-old's career highlights include being part of the security detail for Bollywood actresses such as Priyanka Chopra, the star of the US television drama series "Quantico", Preity Zinta and Vidya Balan.
Mehrunnisha is no stranger to smashing stereotypes.
Only her mother's insistence allowed her to further her education beyond primary school.
But when her father's stock market losses forced the family to move to the capital, Mehrunnisha, still in college, became the breadwinner for a household consisting of parents, two sisters, and her elder sister's three children, besides herself.
"But this does not affect me, because my mother and father have faith and confidence in me, and I know I am not doing anything wrong."
Her younger sister, Tarannum, 27, also works as a bouncer at a bar just a 5-minute walk away from her own workplace. Together, they earn 30,000 rupees ($465) a month.
"I am very proud of what I do, it's not an easy job," Mehrunnisha said. "Taking care of people, especially women in a club, is a very big responsibility."
Customers seem to agree.
"If I come here and I see a female bouncer, I feel a lot safer," said one regular patron at Social, Nikita Lamba.
"Mehrunnisha is pretty kick-ass. She is good at what she does".
