I have always loved the complete range of the Lays series and specially the special flavor series which is launched during world cup seasons and all. But whatever flavor may come up, I would always stick to the magic masala flavor which really is my favorite among all the flavors.
This really has a desi flavour added to it. I love it during watching TV, but its really difficult to share it:p . Sometimes I also have it in my lunch with rice, it might seem weird, but I really like it when I do not have any kind of side dishes. Affordable price and apt packaging to keep contents fresh.
