I just read a post that mentioned it's best to drink bottled water in Paris to avoid upset stomach the first couple of days. This was the first time I'd heard the tap water in Paris could cause problems. I've only read that the tap water is just fine to drink. So, I'm wanting to hear from as many people as possible about their experiences with this. We were hoping to not have to spend the extra money on bottled water if at all possible, and just order "un carafe d'eau, s'il vous plait" in most of the restaurants.
