Cider
Cider is actually spelled Cidre in french. 
And it is: LA merde not LE merde. French gives gender to words. To make things harder to learn. lol. So merde is feminine.
I’m french speaking so for me, it’s my english that sometimes needs to be fixed. So no resentment 
That said, some usefull words or sentences:
Merci Beaucoup (basic… means Thank you very much).
Bienvenue (said when someone says merci. it’s like you (re) welcome)
Dont bother to ask your way (like: Pouvez vous m’indiquer le chemin pour aller à…) they will get you lost. Even if you understand their indications. I’m french speaking, and went to Paris 5 times, never got usefull driving directions.
We, as North American people (USA and Canada) need to remember that the holly rule “client is always right” DOESNT APPLY overthere. So it is NOT because you pay or you are a client that they will lick your boots and knees down. They can be really pissed off by tourists who thinks they own the place. And won’t get fired by the boss to do so. Just another way of thinking, wich I personnaly find GREAT since I used to work with public and sometimes wished to be able to do the same haha. So this is something to remember carefully when travelling there. Be nice they’ll probably be too. Be mean, they WILL too, without any doubt.
Then, sometimes it is also better to just ask in english after apologize like: Je suis désolé, je ne parle pas très bien français, parlez-vous anglais? Because sometimes, bad spelling hurts their sentiments more than just not speaking french at all…
Ok, these are suggestions, not really phrases… But well.
Others:
Pourrais-je avoir le menu s’il-vous-plaît? (at the restaurant, to get the menu)
Pourrais-je avoir l’addition s’il-vous-plaît (To ask for the bill at the end of your meal, if you are a group and need all separate addition, ask instead: Pourrions-nous avoir les additions s’il-vous-plaît? Séparément).
In France, 15% tip is INCLUDED in your bill automatically. If you are VERY happy with your service, or wish to get really good service because you intent to come back often to this particular restaurant when you are overthere, you can give extra tip. But it is up to you.
Be sure to always have some change in your pockets. Often going to the restroom is not free. There’s often (in nice restaurants etc.) a lady sitting near the toilets room asking you to pay then she will wash the door knob and sink and toilet before and after you go pee. Or sometimes in cheaper restaurants, there’s lock on the toilet’s door so you have to insert coins to unlock it. PITA when you have no change and a 5yo child with you…
But yes… food is divine.
