Based on TA reviews we chose to eat evening meals here twice during our (first ever) week in Jersey. The fact that we ate there twice is a positive indicator.
Overall it was a good choice, but IMO it didn't have that extra 'something' that we were expecting. Not a problem, just that perhaps we were expecting too much. If TA would allow it (which they don't) I would rate it good, rather than very good.
Quite a busy / buzzy place - definitely book in advance.
