Well if you are on your way to or from Wales and you are low on gas(oops sorry petrol) or diesel then by all means stop and fill up. However if you want food and have enjoyed the experience at other service areas on the motorways in the UK — don’t!!! Jump back in your car and drive away quickly All they have to offer is a tiny Burger King(really???) and a Costa coffee shop with unskilled baristas. I fail to understand why Costa is so highly rated in the UK. But anyway — gas up if you have to — eat elsewhere!!!
