The Hawthorne is back at Umami Burger, this time with more surprise appearances from sexy singer Mayer Hawthorne himself. Hawthorne teamed up with the burger chain for a signature burger last year, but this time it will be at both The Grove flagship and in Hollywood starting July 16, the day his new album, Where Does This Door Go, drops. There will also be slider versions of the burger - a beef patty topped with cognac-infused parsnip puree, cognac fondue sauce, hatch chiles and chile straws - on the new Umami Truck on July 10 and 17. And Hawthorne himself will be there to say hi. Find out where and when on his and Umami's Twitter feeds.
