Kimchi (via JoeFoodie) is a fermented cabbage dish served primarliy in Korean restaurants.  Ethnic cuisines usually accompany have a fermented food with each meal.  Fermented foods, especially lacto fermented, aid in digestion (Fallon, Nourishing Traditions, 94).

Kimchi is a spicy sauerkraut.  Sour, crunchy, & peppery - it is a perfect compliment to full flavored, rich Korean dishes.  Not all kimchi is created equal, of course.  The version pictured is made in house at BiBimBap in Novi & is delicious.  Layered like a lasagna, it is crisp, tart, & firey and very fresh.
