I have to admit, my guilty pleasure is McDonald's, which was founded in 1940.
what's your best food item there/
Although they are known for their hamburgers, I think I much prefer the cheeseburgers.  
 I love the Big Mac it's so tasty I could it lots.
The Big Mac is definitely one of McDonald's signature products.
 I love there fries also there cooked well and always freash
Me too.  I especially like that they are salted just after cooking, but not too much.  Sometimes they can be too salty.
