Years ago I considered this place a top spot but it has lost a lot of its attraction for me these days so only stop for a 45 and a quick bite occasionally if at all these days. Haven’t night stopped for years but the few day visits I’ve done the barriers were open.
Seems to be big for the lads needing a tank or fridge wash and an unbelievable amount of EE and other foreign trucks always parked on the verges of the access road for some reason.
