  • Absolutely wonderful store, everything is reasonably priced apart from the actual m&ms that were overpriced, altogether a fun shop, and fantastic friendly staff

  • How they do business baffles me, making anything to advertise their product. The staff were friendly and it got us out of the rain on the plus side

  • M & M World is the largest candy store in the world at 35,000 sq ft and occupies 4 levels of everything M&M. You’ll find M&M’s chocolates – of course! – and all kinds of related merchandise, like t-shirts, mugs, toys, key chains etc

    You can even print your face on the candy chocolates! It’s a great place to get all kinds of interesting of souvenirs.

    If you’re visiting with kids, they’ll think they’re in candy heaven! It has the world’s biggest candy wall and 100 types of M&M chocolates! (You didn’t know that, right? Well, now you know)

    For me, the best part is, you’ll get free M&M’s samples! Enjoy!

  • Very busy shop. Wow. The colours really pop. So many different items made from M&Ms. So much choice for everyone. Not just children. I really love the tubes of coloured M&Ms. It looks so cool. Each floor has checkouts, so getting through the payment section is very quick. Also, staff are very happy to help and have a great smile while serving you. Will be returning.

  • Just a merchandise store for M&M’s. They have some unique colours, but unless this is really important, forego getting the pick-your-own as it is two and a half tunes more expensive than the supermarket. You would think that this store would be able to have a bulk price. If they could do chocolate at 50p per 100g this would be a destination location rather than a “drop in if you are passing by”. Give it a miss.

  • An interesting place to visit but not on a Saturday evening in August. Absolutely packed, could barely move, no free tasters. If you love M&Ms I’m sure you’ll love it…if not, it could waste some time if you are bored and want to experience how it feels to be an M&M packed into a tube.

  • Nice place to take the kids. Kids love all the merchandise and esp the chocolates. Good photo ops. Staff are good at their job.
    Can be a bit pricey for the products. Gets very busy regardless of what time or day of the week you go to. If you have young kids make sure that you are holding their hands tight as people just push them out of the way
