Thank you for sharing the photos, looks like the place is packed with goodies! I would personally lean towards picking up the Atari King Kong cart, and also see pricing for Akumajou Dracula and Gimmick! on the Famicom (assuming they aren't reproductions which seems common).
Where in Canada are you from? I've always wanted to purchase some bread and baked goods from Thailand (site content might not be for the squeamish!)
