The 85/1.8 is a great lens, very useable wide op (ok, i only do stills, but a great lens is a great lens).
But is 85mm the length you want? Even on a FF body, it's going to be head+shoulders only unless you can step back far enough.
You said 'cooking show', i'm envisaging a kitchen table setup on a sort of static shot, with you (/the chef) running between the far left and right of the frame cooking and cutting and talking etc. For that kind of shot i'm thinking wider angle would be more useful, 35-45mm FF. You'll probably have to stop down a fair bit unless your focus-puller has really fast hands too.
But hey, if it's the length you want, you can't get much better than the 85/1.8 for the price.
Also, I have a lot of manual lenses, no nikons though, but i've heard good things about the nikon 50/1.4. also consider Asahi Pentax Takumar lenses, zeissy-smooth focus, you can de-click apertures easily, $100-150 or so for a 50/1.4 and 35/2, up to $2-300 for their 85/1.9, down to $50 for a 35/3.5 or 28/2.8. Not a dog in the bunch, as long as they're well taken care of.
