We hadn't planned to visit this place but when we came across it accidentally we decided to pop in. The place looks like a theme park for M&M's. They say it is the largest candy store in the world with all sorts of merchandise spread over the building's four floors, everything being dedicated to M&M's: souvenirs, bed& bath, kitchen wears, stationery, bags, clothes and jewelry.
If you have small kids they will definitely love the place. If you are a M&M's fan or you yourself are still a kid at heart then too it is worth a visit.
