I drove here when I stayed at the Palms over a weekend a few weeks ago.
I'm not sure if it was Worth the drive, but it sure was good! There was no line, so the lady helped us decide what to get. We got a somewhat of a cinnamon horchata rice drink which was decent. It tasted exactly what it was named.. forgot the name though!
I wish i tried their expresso though, I had to drive down to Starbucks to get my crack for the day.
