Ugh. First: The vegetarians that I know don't like meat. So making a veggie burger that tastes like the thing they don't like is just dumb.
Second: When I tasted an Impossible Burger, it was awful. It tasted like a horrible veggie burger.
At the places that I've tried it, the staff usually apologize as I order it, and warn me that I probably won't like it. They all tell me that the ordinary veggie burger that they used to serve was better.
At that point, they hint that they were strong-armed by their distributor to server it.
I personally reduced my meat consumption for environmental and health reasons, but when I want a burger, I get a burger.
