Delhi folks where do you go when you just want to sit somewhere quiet and be left alone?

Not looking for pubs, malls, or the usual Coffee cafe recommendations. I mean a genuinely underrated peaceful spot where I can sit alone for 1–3 hours, read, think, listen to music, or just do nothing ..but watch the world

Safe for female
