General guidelines used for food ratings:
DISGUSTING: It was inedible or almost inedible.
BLEGH: I didn't like it. I probably wouldn't eat it again even if someone gave it to me.
OK: I might eat it if someone gave it to me, but I wouldn't buy it myself.
GOOD: I liked it. I would probably buy it or have it again, but it's not quite delicious.
DELICIOUS: YUM! I will definitely have it again.
