I have been to this place many times on an evening and always find the food superb.
The decor has a contemporary yet historic feel to it and is very clean.
When I have been during the day for a coffee and cake, the place has a very relaxed feel to it, and the staff are very courteous and yet not in your face like some places.
When I have visited on an evening the atmosphere changes and has a somewhat elegant feel to it. If you are in the area it is well worth a try.
