I’m using a Yum rating factor with a maximum 5 Yum rating based on the following criteria:
Atmosphere is the easiest to rate but the most intangible. It has to be comfortable and it has to be positive. I don’t want an angry barrista making my coffee and I don’t want an indifferent server pouring my wine.
Something special is either a general wonderful feeling or a knock you in the eye kind of extra.
