I was in Las vegas back 6 months ago or so for a special family event and we all ate at Picasso in the Bellagio. There was a fixed menu choosing one of 3 items for 1st/2nd/main and one of the options on the main was Fallow Deer. Me being the adventurous kind decided to be 1 out of the 2 people in the group of 25 or so to order it(other person got it medium well and I got it medium rare under the advice of the server) It was easily the best meat dish I've had in my life and after I let my brother sample it he was shocked at how good it was(save for him liking his food done medium and not seeing any red at all. Obviously due to us dining at Picasso, it might not just of have been the Fallow Deer but may of as well been the Chef. I'm sure there's somewhere in Los Angeles that serves it, the question is where and who does it best?
I would normally mention a price limit but this being a special dish in my dining experiences and the fact that it's relatively hard to find among game meat in general leaves me to at this time set no limit unless it gets really crazy. Distance would probably not be an issue unless it's a dish only available on saturday night in DTLA(#Drunkageddon). The only place I've heard of that would possibly have it is Saddle Peak Lodge but due to it's remote location, I'm not sure if it's mostly visited to it's remote charm.
