I think in terms of like to like, only Kino remains.
the demise of Borders to me...is the lack of online browsing, lack of Chinese & other lang books and of course their choking rental.
ditto for Page One - choking rental.
actually it is not messy at Page One, you just need to know where to go.
If talk about messy, you find Kino Taka messier.
Big Bookshop -honestly I dun even know what is their selling point - stationery, some cheap picture books,?
Popular is surviving only because of textbooks and assessment books
