M and M World london

M and M World London (otherwise known as M&M World London) with Roam the Gnome!

When you head into Leicester Square in London, the kids will not miss this rainbow-coloured building. Be prepared to enter the rainbow hyper-colour world of M and M World London. There’s quite a bit to do and see over 4 floors (a total of 35,000 square feet of M&M’s!), 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. 
If you or the kids are die-hard M&M lovers though, don’t miss it. There’s lots of photo opportunities, and you might even MEET an M&M character in the plush!

Create your Own M and M World London Mix

The pick-and-mix place downstairs is where the fun really begins. You and the kids can fill a bag with your own selection of M&Ms in all the colours of the rainbow. Pick your favourites from over 100 choices! Price is by weight, so don’t go too overboard. It’s a fun gimmick but gather your bigger chocolate supplies at the supermarket.

Mix Lab Ordering Station

If you are feeling fancy, you can even order a Bespoke Mix of your favourite colours and watch them being dispensed by a team of Mixologists behind glass in the M&M laboratory! You can even add messages to your M&M’s for that really special occasion.
