There is a bar menu, but most guests will elect to try one of the two fixed price menus, about £30 or £38, depending on your choice, as of this writing.
The problem with the old country houses is that in order to make them work in the contemporary world, those large bedrooms have to be cut back a bit to add the ensuite bath and modern heating and plumbing. The result at Monk Fryston Hall was, for us, a somewhat tight but otherwise very comfortable room, in an old country house brimming with history. By turning themselves into a hotel, Monk Fryston has found a way help keep the doors open and the house in reasonably good shape. You'll see an occasional crack in the otherwise beautiful old plaster, but the whole place has a feeling of being at home - in a very large home. The staff were all very helpful, and dinner was good. There is a beautiful garden outside, and sure enough a wedding party were arriving the night we were there. I imagine it would be an excellent venue. There were plenty of power points in our room, and the free Wi-Fi was one of the best we have seen!
