John Mayer & Adam Levine: Katsuya Cravings

John Mayer carries out his iPhone after dining at Katsuya restaurant on Saturday night (September 5) in Los Angeles.

The night before, Maroon 5 rocker Adam Levine was seen eating at the same hotspot.

Moments ago, John took to Twitter about the good time he had last night. The 31-year-old singer tweeted, “I’m a little hung over. Don’t get me wrong, I could still save Nakatomi Plaza if I had to.”

FYI: Nakatomi Plaza is in reference to the building that John McClane (Bruce Willis) saved from a terrorist attack in 1988′s Die Hard. Remember Hans Gruber (Alan Rickman)? His best line: “Now I have a machine gun. Ho ho ho!”
