If you're wonderiong why there seems to be a long, well-stocked bar in the back, that's because the Palace was in the airport.
The decor is described as "regal early San Francisco setting," but how those seat cushions relate to the 19th century is anyone's guess. As for the general idea of Regality, well:
"Pancake is King! Fourteen varieties of the finest pancakes in the world."
I've long held that there is only one variety of pancake. The rest is just toppings.
