McDonald's Filet-O-Fish Vs Burger King BK Big Fish Sandwich

Up until last week, I hadn't eaten a fish sandwich from a fast food restaurant in approximately two months. More often than not, when I do order a fish sandwich from a fast food restaurant, it is a Filet- O- Fish (R) sandwich from McDonald's(R). Last Friday however, I was at the Burger King (R) restaurant located close to my apartment, when I remembered that as part of a summer promotion, their fish sandwiches were "Buy one, get one free" on Fridays. I had never eaten a Burger King (R) BK Big Fish (R) sandwich before, in fact, I had never even seen one. But, because I love a bargain and was in the mood for something besides burgers, I decided to order the fish sandwich(es) "to- go". As soon as the friendly counterperson handed me the bag containing the two fish sandwiches, I was surprised at how heavy the bag was. As I walked away from the counter, I peered into the bag and saw that the Burger King (R) fish sandwiches were quite large. In fact, they appeared to be huge. I looked- up the BK Big Fish (R) sandwich on the wall- mounted nutrition chart in the restaurant and read that this fish sandwich weighs over four ounces.
