The Jardin des Plantes is a large botanical garden on the left bank. French gardens differ from American gardens in that the paths are invariably sand rather than asphalt or paving stones or grass. This results in dusty shoes, which is a little irritating. Also, French gardens seem to be more formally structured than American or English gardens. This garden has a labyrinth which couldn't fool anybody since the path is a simple spiral. Nevertheless, it's quite charming.
The Arenes de Lutece are the remains of a Gallo-Roman ampitheater. It's surrounded by a very pretty park. We saw men playing boules in what used to be the arena area.
Dinner was at a Laotian restaurant where I had toasted rice salad and the co-diner had a shrimp dish. Now I have to figure out how to make toasted rice salad. We'll see if Google can steer me in the right direction.
