McDonald's changes its main menu every few weeks to attract new customers, but changes to the Happy Meal don't happen often.

The shake-up is the biggest change to the Happy Meal in more than a decade - but the items aren't available everywhere just yet.

Four new items are coming to the Happy Meal range as part of a UK trial. The Sun's Chief Consumer Reporter James Flanders put them to the test.

Five bite-sized pollock pieces coated with crispy panko breadcrumbs. They were delicious. You don't feel short-changed either, as each serving is packed to the brim with tender white fish.

Kids will be able to choose between a beef-based burger and a chicken alternative for the first time. The chicken burger is crispy but not greasy - a great McDonald's staple.

Mayo chicken

Kids will now be able to pick between three new flavours - banana, chocolate and strawberry. These drinks contain no added sugar or artificial flavours and they certainly taste that way.

The new McFreezy dessert is made with fruit juice and puree and is available in orange or mango and pineapple flavours. They taste very fresh and not overly sweet.
