Since my childhood days I am a fan of Britannia 50-50 biscuits. Though other brands also came up with the same type but I have always stuck to Britannia because I find its taste better than any other biscuits.
One thing that surprises me the most is that its quality remained consistent throughout the years. I almost take them along with me to my office where I have my daily evening tea by dipping these Britannia 50-50 biscuits in it. I simply loved it. Moreover, its quite healthy with zero fat.
