Police said a car and gun were found near the bridge, and that a man was seen on the wrong side of the barrier.
She told Sky News that she was preparing for the Valentine’s dinner service when she heard two loud bangs that she initially thought were fireworks.
About 30 people were at the pub for dinner, while 20 more were in the bar as the incident unfolded just after 7pm, she said.
