I'd rather eat a falafel pita wrap, or a Indian spicy potato burger, or a bean burrito. There's plenty of great vegetarian food, no need to torture plants to become something else.
I'm also really picky about meat and I love vegetables.
It was right next to campus. Vegans were everywhere. My guess is that, as a vegan, you probably don't think to go to a fast-casual place with the word "Burger" in the name, when there's two falafel joints around the corner. Another guess is that, as a college student, you would rather not spend way more to get an imitation, when you could just get the real thing.
As a line cook, Impossible burgers are a pain in the ass. You have to handle them with more finesse than normal burgers, or they crumble. We had to run the second flat-top at a lower temperature for them, because they would sear horribly if you ran them at the normal birger/turkey burger temperature. As a result of the lower temperature, they cook slower. Any niche ingredient that rarely gets used inherently causes hiccups in the process, slowing down the kitchen.
I tried an Impossible burger on a meal break once. It didn't really taste like a burger, more like "someone mixed some bison with a bunch of black beans and salt," but it still tasted great. The thing is, the normal burgers also tasted great, and they cost less (to the business and the customer).
If I wanted to eat plants, I'd go eat plants. I don't feel the urge to eat plants that are pretending to not be plants. That said, if Impossible could undercut ground beef prices, then they might be onto something. Good luck undercutting ground beef prices in the Midwest, though.
