I must be the only person in the world to not like parle g, I mostly consume britannia products like milk bikis, Tiger etc.
The only time I bought them was back in 1999 when they were selling shaktimaan stickers along with parleg.
I tried consuming it but I couldn't finish the packet as the biscuit was too sweet and the there was some sort of smell coming from the biscuit I thought it was a problem with this one particular packet but other parleyg's that I bought smelt and tasted the same.
Some people consume it with chai I have never tried that combination. All North Indians I know love parle g but in south India you can even find them in stores. Tiger biscuits are famous in the south it seems. I don't like parle g.
