Librerías Gandhi

Has a great variety of books.

A little disorder on the children book section, but otherwise a great bookstore. Lots of variety and a friendly staff. They also have a Ticketmaster counter if you need to buy or pick up tickets.

They hace a great variety of book on all kinds of topics. Also the staff is usually pretty kind.

I go fairly regularly to sit down and read in the cafe which is pretty good and has a decent selection but it's kind of loud for what's essentially a cafe in a bookstore - a place where you might expect to be able to read fairly peacefully. There's an ok selection of English language books as well. Parking is pretty limited and so is seating in the cafe. If you can find a space for the car and to sit down though, it's quite nice!

Good costumer attention. If they don't have a book in store they will order it online and have it in a few days (won't charge shipping).
