Umami Burger is a Los Angeles–born gourmet burger restaurant concept founded by Adam Fleischman that elevates casual dining by centering on the savory 'umami' taste through chef-driven patties, inventive toppings, and signature condiments. Known for its toasted buns, umami-rich ingredients (like aged cheeses, caramelized onions, miso and truffle), and design-forward service, Umami Burger has expanded beyond its flagship to multiple formats while maintaining a focus on flavor-forward, hospitality-led dining.
