I'm out to the west coast of couple of times a year and always bring back burgers to New York. Mode of transportation = Freeze them. You'll never get that same experience but it's the closest thing to it. I've tried to bring them back on the plane but I just end up eating them.

I believe there are some Five Guys located in Chicago. That'd be the closest thing to an In & Out burger here on the east coast/midwest. The thought of a double-double, protein style, animal style has me on cloud 9 right now.
