"Last year it was happening all the time, but this time was harder because it is just before Christmas and our tills with the menus loaded were smashed," Sinclair said. "It is the last straw, we have just had enough."
One thief broke in several times and was caught on camera and arrested. He was jailed but started breaking in again when he got out. "We noticed the same type of break-in happening again and sure enough it was the same person," Sinclair said.
They also posted pictures on Facebook to identify a couple who had done a "dine and dash" at several restaurants.
"We have had an amazing response from people, not only to help catch these people but also the support we get.
"It is heart-warming to know people in the community support us and want this type of thing to stop."
The restaurant had a full security system with an alarm and cameras but thieves were quick to grab what they could and get out again.
Sinclair said staff now removed all alcohol from the bar - more than an hour's work at the end of the night. "It is a real inconvenience but we want to make this as non-beneficial to these people as possible."
