What can I do in Paris on Friday?

I’m coming up to Paris for a meeting at 2pm, but I arrive at Gare de Lyon at 10.42am.

I’ll be going to the Luxembourg metro area for the meeting. Does anyone have any ideas what I can do in-between time (that doesn’t involve a huge amount of walking)? My list so far extends to: Read Kindle in Lux Gardens, have picnic lunch.

All ideas welcome. :slight_smile:
