Hi. Nice to meet you. As i introduce myself, i will tell you i am a "junkfood" junkie with McDonald's being my fave!
McDonald's is a fast food company that was founded in 1940.
Wow, really ? i did not know that they have been around that long although i do have fond childhood memories of the happy meal. :)
A "Happy Meal" is a form of kids' meal sold by McDonald's since June 1979.
Do you like happy meals or what is your favorite mcdonalds item?
Not a big fan, but my kids like the main item (typically a hamburger, cheeseburger, or small serving of Chicken McNuggets)
my favorite is the big mac. Mcdonalds is super popular for that special sauce , lettuce , cheese, onion on a sesame seed bun. I love them
The was introduced in the Greater Pittsburgh area, United States, in 1967
Really ? Is the Greater Pittsburgh area where McDonald's was founded? 
No, the chain originated  in San Bernardino, California, United States.
thank you
