Other Things Worth A Mention:
Get a baguette or two or three while you're in Paris. One baguette will set you back a Euro. That's it. (It'll make up for the expensive long black or macchiato you'll be ordering at the hipster cafe.)
Do learn a few French phrases. I opted for "Hello. I'm sorry. I do not speak French." or: "Hello. If you please, do you speak English?" I also used "Check, please," "How are you?" and other basics. Don't be surprised to get a "Ma'am," "Miss," or "Mister." It's part of the polite and formal nature of Parisians.
Try the pastries. Even if you "don't do gluten or dairy or sugar." Unless of course you're allergic. But they are really inexpensive and really good. I mean, how many times are you going to eat a pain du chocolat in Paris?
I read on other blogs about how walkable Paris is. While that's true (and I often got in about 7-9 miles a day on foot), don't hesitate to take the Metro around too. It's a very good Metro and easy to navigate.
Don't go in August like I did. Places shut down and it's full of tourists. Go on an off season/month. That said, the weather was great....
Watch your step. Dogs/Cats/Humans/Other Creatures tend to leave messes around on sidewalks...
Hallelujah as covered by Jeff Buckley:
Just a song I love. No relevance to Paris whatsoever.
