INSIDE: Enter the World of M and M World London Leicester Square here. 
When you head into Leicester Square in London, the kids will not miss this rainbow-coloured building,  M and M WORLD Leicester Square.

Be prepared to enter the rainbow hyper-colour world of choc.

There’s lots of things to do and see over four floors at M and M store, (a total of 35,000 square feet of M&M’s!), but only if you can bear the over-the-top merchandising push.

There’s no getting away from it, and you’ll see the same stuff again and again repetitively over different floors.

BUT if you or the kids are DIE-HARD M&M’S CHOCOLATE FANS, don’t miss it.

There’s lots of photo opportunities, and you might even MEET an M&M character in the plush!

But this is also where you can order PERSONALISED M&M’s! 

Take a sneak peek inside M and M WORLD London below.

M&M Shop London Merchandise

The most difficult thing about taking kids to M&M World London is dodging their please for M&M’s merchandise.

They will be overwhelmed by the possibilities, and nagging is likely to commence.

If you do succumb to their persistence, they might like to choose a plush toy to match their personality to an M&M character!

On the periodic table, the code is:

  • red for outgoing
  • yellow for clumsy
  • green for flirty
  • blue for cool, and
  • orange for paranoid.

M&M’S World stores around the world gave the brand a chance to move beyond confectionery into the world of licenced products, and give it a place in popular culture today.
