Cadbury Picnic Bar, is one of the oldest and most-loved bars in the Cadbury chocolate bar range. Its probably the favourite son, but were not really meant to say that sort of thing. Its gone through some changes over the years, but essentially looks and tastes as good as it did when they perfected it back in 1958. If youre into nuts and wafer and chocolate and rice crisps and caramel, then BAM! You have come to the right spot.
