> The Livraria Lello where this is located, is definitely a bookshop.

And barely a bookshop at that, more of a tourist attraction. You need tickets to enter, and the main selection of books are classics, mainly public domain iirc. They have more recent/interesting books but only as decoration (I asked to buy a Naomi Klein book, they refused to sell it). Most people are just there to take pictures because the stairs inspired Harry Potter.
