My latest obsession - Depaul's coffee. Apparently this cold coffee brand is a Delhi institution. It's bottled in central Delhi and then sold at the store there or in certain restaurants around the city. It probably wouldn't pass any safety inspections (bottle not sealed, cold chain unlikely), but omg it tastes so good I don't even care.
p.s. A note about cold coffee: It's not iced coffee, it's not an iced latte, it's something altogether different and magical. It tastes like a milkshake and has the consistency of chocolate milk. You can get it at any coffee shop or restaurant in Delhi, not just Depaul's. I highly recommend trying it if you happen to be passing through.
