it's open most nights after the other places are closed... and you can't do it all in one day anyway...pick and choose... get to know the Metro.. it's fast and cheap... eat at Brasseries.. they're Bars next to cafes that have a cut down cafe menu for cheaper.. and it's the same kitchen... if any way possible... Road trip to Chartres for the Cathedral with the statue of Melchezidek next to Abraham.. and more 12th century glass than anywhere else... Mont St Michel is a day trip or overnight.. and it's maybe the top spot in France... close to Bayeux for the Tapestry and Omaha beach next door...
