Life in the Fast-Food Lane

After a good-natured argument about the best fast-food restaurant in town, Karen and Jerry realized that there was only one way to settle the matter- to visit each of the five restaurants in turn and sample the fare at each. At each step, they placed an order for the restaurant's signature sandwich (no two of which have the same name) and also asked for a different extra item (in one case, extra onions) on each. After sampling all five sandwiches, they still couldn't agree as to which was the best and began a new argument instead - which company makes the best antacid ! From the information provided, determine the order in which Karen and Jerry visited each restaurant (including Pig-Out) as well as the name of the sandwich they ordered at each and the extra item they requested on each sandwich.

1. Karen and Jerry visited Belly Buster immediately after the restaurant where they ordered the Deep-Sea Burger and at some point before the restaurant where they requested extra sauce.

2. Their third stop was Fast Fry which wasn't the restaurant where they requested extra tomato slices. They ordered the Goliath sandwich with extra mustard.

3. The Big Daddy sandwich wasn't the one purchased at Burger D-Lite (which wasn't their first stop). Their request for a sandwich with extra cheese wasn't made at the first stop.

4. Karen and Jerry bought the All-American Burger at some point before they bought the meal at Big Joe's, which they purchased at some point before the sandwich on which they requested extra tomato slices (which wasn't the Double Whammy).
