Conor McGregor's world domination continues.
If $50-100 million and an escort from Drake weren't enough to make Conor's weekend, the UFC superstar now has an epic mural outside an Irish pub ... 5,000 miles from Dublin.
Jonas Never -- the street artist behind the (vandalized) LeBron James mural -- started the project earlier this week ... utilizing a brick wall outside O'Brien's Irish Pub in Santa Monica.
Jonas tells us the super realistic mural took him about 18 hours in total to paint over the course of 3 days.
