Les Mots is packed with books, LBGT-themed and others, and they always seem to carry the top 5 books I've been looking for lately; classics as well as new stuff; everything neatly organized. They have a great wall of magazines, too. And a basement.
At the moment all I want is for that wonderfully nice staff to start selling tote bags with their logo, in the appropriate blue colour. It would be perfect in my collection, and I would carry it everywhere with me, showing it off.
By the way, on that same extraordinary corner is:
Amorino (the best ice cream in Europe), Saveurs de pains (a boulangerie that does fantastic baguettes with gruyère & ham and a mean café crème) L'étoile manquante (a great hangout café/bar with an otherworldly salad of fresh fruits and cheeses with mustard dressing - Salade d'Ètoile).
