We didn't use the grills during our stay in September but they do look very nice. Somewhere I read about the grilling tools but can't remember what it said! Sorry. I do suspect the sign was in the grill area.
As a side note, the booklet in the cabin that lists dining options has a mistake in it. Geyser Point opens for breakfast half an hour later than stated. I walked over at the opening time listed only to have to return half an hour later. Our cabin wasn't too far from GP so it was no big deal but I would have been ticked if our cabin was at either end!
