John Mayer hat cowboy hat pants green shoes brown belt shirt blue facial hair beard mustache scruffy Katsuya

Wait -- which John is it??

John Mayer seemed to be taking a page out of Johnny Depp's style guide as he went to dinner at Katsuya in Brentwood on Saturday night. Either that, or he's been watching a lot of Indiana Jones lately.

All he needs is either a snazzy mustache or a whip to complete his look of choice.
