Paris Indoor Walk : visit the Galeries et passages couverts parisiens

It's raining or/and you want to feel back in 19th century, plan a walk that will go through as much "passage couvert" you can - a lot of them are in the 2nd arrondissement.

My favorites : passage du Grand Cerf (for shopping), galerie Vivienne (to be amazed), passage des panoramas (to eat) and Passage Colbert (a secret one, great to relax)
