The Derby Arms is a pub that was once famous (in the early 1990s) for gypsies and fighting. The transformation to gastro-pub was very welcome in the early 2000s but a decade later the pub is in obvious decline. The food remains good but the service has become poorer and poorer. On our most recent visit today staff were openly complaining about not being given breaks every six hours (an EU legal requirement).
There is no apparent management in place and orders regularly go missing or have drinks and dishes missing. You should expect to have three or four different servers who do not communicate with each other and will not take responsibility for your table or orders. At some point during service you will almost certainly be abandoned and have to ask someone where your meal/drink/bill is. It is not unusual to wait for thirty or forty minutes for the bill to arrive.
It's a genuine shame that this former gem has lost it's quality over something as straightforward as competent management. Expect to see the gypsy fights on the patch of grass in front of this pub returning in the near future.
