Harvey Weinstein showed up in a not-so-effective disguise at a Phoenix restaurant Thursday night, because everyone in the joint made him.

Weinstein was wearing a blond wig, orange makeup and a baseball cap when he showed up with a male companion at Chestnut restaurant. We're told he asked for a private room ... problem was, the room was all glass so people in the restaurant could see him.

Weinstein's hat was inscribed 2:24. There's a 2:24 Bible verse that reads, "But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him."
