...And by all means take you biggest tripods and large format cameras with you. The best place to photograph is the National Assembly building next to the Orsay. The city is really clean, except for one place the tour guide kindly pointed out, American Park. It looked like a run down dirty needle park. They seen to love Americans. Tip generously they don't have a very high tax on anything. I think its 20 to 30 percent. I saw a waiter go to the manager with the tip I gave him and he said can I keep it. The manager seem to split it with him, so slip the tip into his pocket.
Really this is humbug. The American Park is really really dirty but Paris is clean and friendly and tipping is small. The tax is high but it's their system. The best thing in Paris is the Louvre. After that everything else is just nice.
