Caught on video surveillance, the 200 pound deer's visit lasted less than a minute where he eventually followed a server outside the back patio through an open door, reports WYFF 4 News.
Adam Buckner, manager of the Taco Mac in Alpharetta, Georgia told the Atlanta Journal-Constitution the deer crashed into the restaurant at about 3:15 p.m. Sunday and exited the restaurant when a server opened the door to the patio.
"When I got the phone call from my general manager, I thought it was a joke. We're right in the middle of Alpharetta -- right here where Highway 9 and Windward Parkway meet -- and there are no woods or anything like that," Buckner said.
But the deer paid a price, losing an antler during his uninvited visit, reports News 9.
This isn't the first time that an animal has entered a restaurant. Earlier this year, a black bear raided a pizza joint in Canada, devouring a slice of pie before being ushered out the restaurant.
