These guys are the Godfather of all UK chocolate bars; the Mars bar has been around for almost 80 years and shows no sign of disappearing from our counters. A substantial chocolate bar, the Mars is no light snack; malt chocolate nougat topped with a layer of smooth caramel and wrapped in milk chocolate. With its iconic black & red wrapper and the ‘Work, Rest & Play’ strap line there is something reassuringly familiar about this chocolate treat. With 259 calories in each standard bar this is not a choice for those looking to watch their waistline, but with no artificial colours, flavours or preservatives you can rest assured the Mars bar is not crammed full of nasties, just the same old great taste!
