A young horse escaped her racing stable in the town of Chantilly, north of Paris, and ran for the nearest café, where customers scampered for safety as she pranced through the premises kicking her hind legs in the air.
A CCTV camera captured how the horse ran from one end to the other of the bar before making a U-turn.
Stephane Jasmin, the bar owner, said no one was hurt in the incident though said he was stunned at what had happened.
Jockey Jean-Marie Beguigne, quoted in the Ouest-France tale of events, said he lost hold of the horse, who had what he called a "runaway penchant".
The animal tore off down the road and across a roundabout before stepping into the bar.
