When I stopped by last summer, the restaurant near the Mt. Shasta supercharger also had a Tesla themed drink- the "Tesla Charge" (Simply Naked Moscato plus Rasberry and Vanilla Svedka. Served with an intense sidecar of curacao infused red bull giving this drink and electric boost.) I didn't care for the drink too much, but it did make for a good photo:
I ordered a Tesla Tini when I was at Harris a few weeks ago. Tesla also has a weird battery swapping facility down there that seems designed to maximize some state tax credits but serves no practical purpose that I can tell.
