If you are ever in Flagstaff, Arizona, stop by the old Galaxy Diner. It's an authentic blast from the past.
The Diner is located off what used to be the famous Route 66.
In addition to some regular diner fare, they also have a menu featuring over 100 different flavors of milkshakes.
What a friend who recently visited there termed, "NIRVANA!" for ice-cream lovers.
And while you're up that-a-way, take some time to drive over to the Grand Canyon.
It's pretty spectacular.
