One of the best chocolate I have ever tasted is cadbury bournville dark chocolate and cadbury is best in doing that. I sont know from where they get it from but the taste is awesome. My sister and my girlfriend both are fan of it’s taste.
About quantity: They give 80gm of chocolate in 100 rs its really cheap compared to its other variants.
About packaging: they can improve the packaging of the product by presenting it in a better packet.
My advice to you is that if you have never had it ever before you so go and tast its once and you will become its fan.
