Why Chai Theory

A simple theory: good chai makes people stay

  • Brewed, not dispensed

    Every chai is boiled to order with fresh ginger and whole spices. It takes a few minutes. We think it is worth it.

  • Kolkata on a plate

    Veg chops, egg devils, kathi rolls and mishti doi sit next to sandwiches and brownies. Something for every craving.

  • Room for adda

    Long tables for friends, quiet corners for laptops and enough space for a pram. Stay for one cup or three.
