One thing remains constant throughout these changes, and that is the presence of the building blocks of an Amtrak Salad. It isn't on the menu directly, but if you follow these simple steps, you too can enjoy this healthy treat.
Step 1: Procure one of the cardboard boxes used in the Sea View Cafe to transport large food and drink orders. This box is one of the few free items you will find on Amtrak.
Step 2: Purchase at least 3 bags of snack food. You can chose from such delicacies as Lay's Potato Chips, Doritos, salted peanuts, pretzels, or the hugely popular Cheetos Cheese Snacks. Be sure to also pick up the crouton of the Amtrak Salad, otherwise known as the Peanut M&M's.
Step 3: Open all bags and dump the contents into the cardboard box, mix thoroughly, add M&M's. You should end up with a salad similar to the picture below.

Step 4: Enjoy with some friends.
