These biscuits are the best now a days, It proved that Parle is the best. I still remember when I was a child and Parle-G was the best in that era. We used to eat it all the time. same story is with Parle 20-20, I cant even have tea if theres no 20-20 biscuits to eat with it.
There are 2-3 flavours of 20-20 but Cashew Butter is my most favourite, Other variants just dont taste good. for example, another falvour Butter tastes too sweet. and I dont like if biscuits have too much content of sugar, but that not the story with the Cashew flavour.
So if you never tried it, give it a try.:)
