The Mcdonalds in the town I work is packed everyday at lunch time both inside and the double drive thru lanes. Burger King, Wendys, KFC, Taco Bell and Dairy Queen are never packed.
I love McDonalds.... Grew up gorging myself on BigMacs, fries, shakes, McNuggets, hamburgers, cheeseburgers when ever I could. mmmmm Back in the day I tried the McRibs and liked the sauce and onions, but was too weirded out wondering what the meat was.
Now in my 50's I have to watch what I eat so I don't turn into an old fat bastid.

I guess I am lucky as my cholesteral, Glucose etc have never been a problem at my yearly physicals so I only worry about getting fat but not my health when deciding what to eat.
I probably average about 2 a month at one of the aforementioned fast food joints... Most days I just eat a crappy salad from the company food service for lunch.
