There are huge numbers of European shops that sell Anime goods but I only know a handful of them so those are the ones I’ll present here.
Located in the capital of the country (Lisbon) with a great deal of stuff, Figures, Gunpla, Manga, Hobby books and other stuff. This is the only national store where I get both figures and gunpla, due to the distance of my house to the capital I only go there some times but thanks to some people that go to Lisbon they manage to bring me the stuff I order. The prices are great, really acceptable in both figures and gunpla which normally are expensive in most of the Euro shops. Totally recommend it to Portuguese anime fans or any other Otakus that are visiting Lisbon.
How to reach: By subway take the yellow line, direction Odivelas and exit in the Lumiar station. Follow the exit to Alameda Linha das Torres and enter the Lumiar mall, store 71.
Ghoul Gear —located in southern capital of Portugal (Faro), has a good deal in terms of mangas and American comics, sometimes they have figures to but they can be a little expensive. This shop is a mixture of both Japanese and American merchandise.
