Nations
If you are ever in the Bay Area, SKIP In-N-Out and find yourself a Nations!

And you HAVE to get a shake and a slice of pie. It's an original and it's amazeballs. Grew up a mile from the original one, so it's such a kick to see their commercials on tv now. (Though they are admittedly low budget lol)

Nothing beats a 2am Nations run for chili cheese fries!
