Patrons at the Beach Road Hotel in Bondi were treated to a bizarre spectacle on Sunday, when a police officer on horseback entered the bar area.

Copywriter and freelance journalist Jonno Seidler, 28, was driving past the hotel with his girlfriend on Sunday when they noticed something very odd.

"I said to my girlfriend, 'Is that a horse inside the venue?' She said, 'No it can't be.'

"We pulled over and she leaned out and grabbed the photo. It was really strange. I've seen police on horses in Bondi before, but never inside a bar," Mr Seidler said.
