I absolutely love this place. It's a really huge place, with tons of books to choose from, no…read morematter your age, including a section for other languages (such as English, Dutch, and Spanish, for example).
The staff is very knowledgeable and some obviously adore books as well, so they'll be more than willing to recommend you book depending on your tastes and/or what you're looking for.
They also have a whole mini-cafe in the middle of the store, with a grand piano to boot (though I wish they'd have someone to play it more regularly, or perhaps have one of those pianos that plays on its own!).
The only thing I have to say against it is how cramped up the entrance is--you have to plaster yourself to the side to let someone else go by, and that while making sure you don't inadvertently make a pile of books fall to the floor (because they're everywhere!).
In any case, this is a dangerous store for me to wander into--I could spend my day there, and I'm always bound to leave with more books than I'd originally intended to buy!
