Umami Burger, LA

Los Angeles is a city of a lot of burger options. On this recent trip, I went to Umami Burger, a regional chain, and I had their namesake burger. It came topped with shitake mushrooms, caramelized onion, roast tomato, a housemade umami ketchup, and a "parmesan crisp". It was a nice and tasty burger, and even the bun was delicious, stamped with their logo.
We also shared, on special that day, a truffled cheese burger on top of a bed of their fries. My friend opted for their Hatch chile burger which also looked pretty great.
