Any time you fancy a treat, you can well and truly count on Marks & Spencer’s food hall to bring the goods. Whether it’s a meal for dinner or simply a sweet treat, good old M&S never disappoints. And some of our all-time favourite sweet treats come from the Percy Pig and Colin the Caterpillar franchises; what can we say, we’re a sucker for a cute character! If you’re also a fan, you may be interested to know that M&S have just launched a brand new friend: the Omballs.
