This is my kind of restaurant.
And because I am a Christian I will spiritualize this post by adding the following passage:
God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground.”
Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds of the air and all the creatures that move on the ground-everything that has the breath of life in it-I give every green plant for food.” And it was so.
See? Mashed potatoes are perfectly legitimate for human consumption.
