When I've been to India the soft drink of choice is a home grown equivalent of Coke called "Thums Up" (no "B"). It truly is vile: it's apparently supposed to taste like a cross between Coke and the betel nut... say no more. Similarly unpleasant and almost radioactive in hue is the lime drink, Limca, which apparently was sold to India by the Italians when it was discovered that it was too carcinogenic for domestic consumption. This story may or may not be true...
