Food Rating Scale
This is the current rating scale I use when reviewing restaurants:
Divine: sheer culinary perfection!
Yummy +2: exquisite flavours that hit almost all the right notes
Yummy +1: mouth-watering like rain
Yummy: a pleasant experience
Average: palatable but many shortcomings
Unpleasant: damn upset my desire to eat
P.S. Some older posts, may still have ratings out of /10 or /20.
