Actually, I think books are becoming trendy. Yesterday, on my way to get my flu shot on the Rue Monsieur le Prince, I walked past a Kitchen Place, very chic, Boffi or something, and on the shelves above the cooking island on display, there was: dishware? No. Shiny pots and pans? No. Books, and not cookbooks either.
Diito. If you are nearby head to Sonia Rykiel on the Boulevard St Germain. If it hasn't changed since I last went by in September, the very elegant couture on offer is, throughout the large store, on two levels, surrounded by bookshelves, tall, wide, and packed with real books, not books by the foot. It's a stage set, but it's worth a look. Lick the window, as the French call window shopping.
