Worth seeing once, and outside is a lot more impressive than inside.
It has lots of lights and bright signs much like a casino (borrowed this analogy from another reviewer).
That store is like a overgrown dollar/Goodwill store that sell cheap and low quality stuff, but with a slight bonus of weird decorations and retro signs all over the stores. It looks a little run down and just not an overly pleasant place to shop. It's not a bad store but there are better ones out there in terms of shopping experience.
One way to improve the place is to start selling quality stuff (preferably Canadian-made items) and maybe redo the lighting inside.
