What: Black Soda at Filter, right next to the blue synagogue, opposite Sabysachi, Kala Ghoda, Fort, Rs 85 for a can.

Why: It’s soda. And jet black. Jet black soda that tastes exactly like soda, which is to say that it tastes like nothing. Can you think of anything more useless, or more irresistibly cool? We couldn’t either. The gorgeous packaging (cans come in four different designs) only adds to the appeal. Kaala Bruni!

When: You want to get into show fizz-ness.
