You may have read in travel folders that Paris is a city that never sleeps. Don't you believe it. At this time of the day there is nothing doing... unless you're working for the department of sanitation. If you want a nightcap at Maxim's, it's too late. It's been closed for hours. If you want to jump off the Eiffel Tower, it's too early. It won't be open for hours. So, if you're looking for a little action, forget the high-rent district.
