Do you know when McDonalds started?
No, I just know it's been a part of my entire 50 year life. and are franchises.
Do you have a favorite sandwich?
They are known for more than their hamburgers, but I like the Big Mac.
I like that one too but my all time favorite is their steak egg and cheese bagel.  Are there many in the town you live in?
We have one in my town.  I am amazed that they have restaurants in 119 countries, though!
Oh wow that is crazy.  Do they offer different things in different countries.
Yes, they offer regionalized versions of their menu to cater to culinary traditions.
