It's bigger and better organized than the stores that pop up only during the season, but it's not overly impressive.
The wig selection is really good, and I wouldn't go anywhere else for those.
In general the costumes are a bit expensive. But that's not really the fault of the store as the MSRP is high these days. You won't find much under $40. Most are in the $50-$70 range.
The staff is helpful and friendly.
I like the system here where the costumes out on the floor are floor models to try on and an unopened bag is presented on checkout. It's annoying at other stores when a lot of costume bags are missing parts, and you won't have that problem here.
