This place is awesome. They have every candy you could thing of (domestic at least) and lots of sodas and other fun things. Its relatively reasonably priced, but some things really didn't seem like that great a deal which was a bummer for buying in bulk.
We went as a tourist activity when we had an hour to kill before going to the airport and it was actually pretty fun.
Be aware there are two buildings (one old, one new) so make sure you go to the right one.
