    Early Saturday evening booking but each time something was ordered from the menu, we were told it wasn’t available. Five times we did this and were told the same thing Reminiscing over the previous 1 visit, it was the same situation. In the end, we left. The floor wasn’t clean and the music was on a short loop of Taylor Swift. Not worth the hassle.
