Umami stands for the fifth taste bud. Apparently, the Japanese invented a flavor that is savory, sweet, sour, and bitter all at the same time. The burgers created here are an art form, a true testament to modern man coming a long way from learning to use a grill. Biting into an Umami burger (or if you want to prove yourself, order the Manly Burger with bacon lard and fried onion straws) is an outer body experience filled with confusion, lust, and pleasure. You won't have any idea what you've just tasted but you know you'll want more.
