Rattlesnake. Not bad, but totally unremarkable - tasted like chicken. Still, I’d recommend it, because the best thing about it is getting to say you’ve eaten rattlesnake.
Pretty much sums up my experience with rattlesnake, as well. The novelty of it was the most interesting part, really.
Though that really applies to just about every "exotic" meat I've had. They all taste like a slightly worse version of other, more conventional meats, and it's immediately made clear why it's not more popular in the first place.
