chuparse los dedos

Remember the Colonel and his greasy and sometimes delicious chicken, and his claim that it's "Finger lickin' good"? I sure do. It's amazing how long those ridiculous advertising campaigns stay in your mind.

De todos modos (anyway), if you want to express the same sentiment in Spanish, you can say "La comida es para chuparse los dedos".

I've only had the opportunity to use this once, but I did manage to get a good laugh from my Colombian co-worker. Although this statement does remind me of the tacos I love so much...
