I had the Impossible Burger at Mocha Bleu and contrary to someone's experience above, it was to put it nicely - disgusting. It did not remotely resemble meat in look, taste or texture. Let's just say I would have taken JJ's raw burger over this any day.
To add insult to injury, they charged $3 (IINM) extra for a slice of cheese (the only reason you buy this in milchig restaurant).
It is no more innovative IMHO than the standard parve soya fare that's popular abroad. I think that all the hype is from vegans who are overly enthusiastic about any meat substitute, not carnivores who prefer a piece of meat, but care limited by kashrus restrictions.
I am not getting my hopes up for the 2.0.
