It is Christmas in July, so therefore they have egg nog as one of their featured flavors. I don't get Christmas in December, or Christmas in July, but its cute and there happens to be a custard eating contest as part of the celebration, which I can jive with.
Our custard wasn't totally frozen- a bit watery for my taste. An adorable place with couches and Wifi, so I'm sure I'll be back (and they'll totally get the fifth star if its actually frozen next time).
