Umami Burger is an oh-so L.A. burger place located in the Space 15 - Twenty shopping outlet on North Cahuenga Boulevard. It offers a modest menu of burgers and a few sides. With most burgers, including the signature Umami Burger, priced at under $10, hand-cut fries and homemade ketchup, it's no surprise the place caught fire with Los Angeles' dedicated burger hounds. The place is quaint, and has a nice friendly vibe. The wait staff is courteous, friendly and right on top of things.
