I've tried an impossible burger (as well as dumplings with impossible meat). As someone who loves a good cheeseburger, it was actually pretty good. Texture was fine, and taste was a little different but nowhere near veggie burger territory. That said, it was in a restaurant so the buttered bun, 2 slices of cheese, and chipotle mayo really covered anything up. Not sure how it would be if I grilled it at home (if it's even grill-able). The main issue, as I think someone posted earlier, is that I don't think the impossible burger is any healthier than beef, so it's more for people who have philosophical issues with beef vs having health benefits.
