Just got my plot put in last night. Mine is mostly for bird cover, but the deer like it.
From what I hear, palatability depends on the variety. I had a 2 acre field last year that was used, but not heavily. Had lots of heads that never got eaten. Across the creek I had 3 small plots in a different variety that the deer supposedly love, and it was hammered and gone early.
This year I'm trying a mix of the two.
