First of all I would like to say that cadbury is biggest dark chocolate brand in india. On any occasion, or any good festival or any meeting cadbury is best to increase sweatness of moment. It is too tasty and pure taste of chocolate. Actually pure chocolate is too bitter, it is not like that but with some more additives like milk it gives you a complete taste.
Cadbury is one of the favourite brand for the festival of Rakshabandhan. You will always find number of varieties and good offers in Rakshabandhan festival.
This aids more sweatness in brother sister relationship. It also come with too many varities and number of package like small, medium, big. It starts from 5 rs. And then according to size and flavour, price increases.
Packaging is also pretty good, that resist cadbury to melt in hot session. However sometimes it melt in too high temperature.
But it is damn awesome.
