Went for a golf weekend with a group of friends and whilst the golf course is lovely it did not make up for the horrendous experience and customer service we received whilst eating here.
A member of our party was served a dessert with a shard of glass in!!
The dish it was served in had chipped before reaching our table, and unfortunately he didn't notice before putting it in his mouth and cutting his lip and tongue. We reported the incident to our waitress and she just took the dish and shard away, not even reporting it to the manager. When we complained again, it eventually took him 5 minutes to come over to us, where he proceeded to accuse my friend of lying and even smiling about the incident. After 10 minutes of arguing with him, he eventually offered my friend a free beer to make up for it, as if it would then all be forgotten. The manager then sarcastically asked if we needed to call 999, as if to make a joke about how severe the incident was / could have been.
This dessert could easily have been served to a young child and the outcome could have been far worse. I was shocked and angered by his response in the whole matter, I have never come across such a rude and incompetent manager in all my life.
The rest of the food was average at best, over cooked pork chop with under cooked, cold chips was the best of three options we were given on the set menu.
