We've been in Paris!
Back in June, Susan mentioned the waiting room at Montparnasse station. On very hot (and very cold) days it is the best place to wait for your train - but not a lot of people know it's there. On days which are neither too hot nor too cold there is an even better place to wait - the station-top garden.
It is accessed by a set of stairs in front of the waiting room that are signposted to a carpark, car hire, and the "Jardin Atlantique".
I quote from Wikipedia: "The plan of the garden is inspired the historical role of the Gare Montparnasse as the train station that connected Paris to Brittany and the Atlantic Ocean. One theme is that of a ship; the lamposts resemble the masts of sailing ships, and there are two elevated walkways on either side of the garden which resemble the bridges of ships. The visitor to the garden is supposed to feel like a passenger on a cruise ship surrounded by a circle of office buildings."

meant to be - preferably the outside, I hope
Next time you have to catch a train to the Loire Valley, get to the station early and have an explore upstairs.
