The frozen hot chocolate itself is a solid Four, but the lack of signage and the long lines make it lose a star.
Apparently I was waiting at the bar on the regular patio which does not place to go orders for over ten minutes. There weren't enough signs indicating you have to walk completely around to the back of the building if you are just getting to go items. Once I got to the back, the line was another 20 minutes long. The frozen hot chocolate was good (next time I'll have them hold the Ready Whip on top) but not good enough to wait that long again. One poor girl was working the register and preparing the food all by herself. Serendipity, you need more help behind the bar!
