"The one I thought had the most umami was the In-N-Out burger, for sure. That's why I think it's so popular. Their onions or something has a really strong umami flavor to it...Just the regular with cheese and the grilled onions. So, once I said that, why don't we try to do a burger that has all the umami in it but more of an upscale experience with better design, and things like that." Umami Burger founder Adam Fleischman, who predicts he'll eventually have 100 restaurants, on the experimentation that lead to his budding empire. [L.A. Weekly]
