Hey GG
Back when I was still back in Milwaukee, there was a restaurant that was put into an old public pool house. It was called the Natatorium, and had a live porpoise show in the center area (the old pool, screened by plexiglass .. to keep the diners dry) The main draw for the restaurant was it’s exotic dishes. They had giraffe, hippo, rhino, emu, etc. The thing I decided to try was lion. (Thought I’d try eating something that would have been eating me if given a chance.
That said, it wasn’t that impressive. I remember it was rather tough, and rather tasteless. The chef must have thought it didn’t have much flavor either, as it came with a side of some sort of sauce. Way too long ago to remember the details.
I would guess mountain lion would be similar.
