Rating System

I need a rating system for the restaurants I review in order to relay a quick summary of my overall experience.  Stars, forks, points,  thumbs up/down have all been done before.  I am looking for something fresh that fits with the theme here, like 5 "vegan cupcakes" for a terrific rating... but not that exactly.  Maybe just descriptions.  How about this, ranked from worst to best:  yuck!, eh, yummy, delish, scrumptious?  The top three are too similar, right?  I may need some help on this one.  Suggestions?
