Food fanatic Stefan Gates and his intrepid Gastronuts go on wild culinary adventures to discover the truth about how we eat, what we eat and where it comes from. Along the way they indulge in hare brained experiments, crazy cooking and eat the world's weirdest food. The Gastronuts and Stefan find out how far their love of chocolate will take them. To test their limits they taste the weirdest flavoured chocolates in the world, and are painted with it. But will they go the full distance and eat it from a brand new toilet?
