I had an Impossible Burger that was cooked like a smash burger, and it was excellent (9 out of 10). I'm not confident that I could tell the difference with an actual beef patty in a blind taste test. They nailed the texture, the flavor, the juicyness, everything.

I know this is different than what many of the other commenters are voicing. My best guess is that the differences in preparation will make or break its similarity to beef. I am a former competitive BBQ judge, so I am no stranger to tasting meats.

Devout meat-eater here. I've had it. The burger is quite delicious. I was really impressed with what they've done. My burger was done sort of in the style of smash and scrape, which gave it a wonderful, crispy texture. The flavor is not exactly the same as a burger, it's more like the abstract idea of "meat". That's not a turn off though, it was quite good.

A couple of times, and it’s nowhere near a real hamburger, but then, neither are a lot of what people get from fast food or buy frozen. It could probably replace the ultra-low-end burger, but anyone who likes actual beef is going to be confused by the hype. Personally, I’d rather eat less beef for health and environmental reasons, an avoid substitutes that try badly to be like beef.

Vegetarian food is at its best when it’s not trying to imitate something it isn’t.

I liked it. It tasted fairly similar to ground beef. Besides the flavor (which can be overwhelmed by spices and sauces in the burger anyway) it was satisfying in the way that a tempe or tofu or mushroom burger is not.

Me and my girlfriend we tried at last week. We really enjoyed the taste. Burgers, of course, come in a variety and also taste quite different depending on what kind of burger you eat. My girlfriend observed that the Impossible Foods one tasted a lot like homemade burgers as they're made for BBQ.

I'd say it competes with regular burgers, it's notably different if you pay attention, but not so salient if you aren't paying attention.

Once they get the price below regular burgers I wouldn't be surprised to see it become a default option.

I've had it several times. The best way I can describe it is as an mediocre to somewhat-above-average patty. It's not going to impress you as being better than a good burger, but it's easily better than bad fast food.

I had one at a publicity event. It was pretty ok, definitely adequate for replacing most of the cheap hamburgers you see around the place, including the supposedly not-cheap ones you get in pubs and such that are actually cheap ones. It probably won't satisfy my meat connoisseur friend, but since I rarely crave a hamburger and the finest steak at the same time, I'd replace almost all my hamburger consumption with Impossible Burgers if available.

Mine had weird after taste - did not like it, but will try it again this week in a different place.

Perhaps my expectations were too high.

Definitely can't come close to a good burger.

But way better than a McDonald's beef patty.

From someone who stopped eating beef a few years ago, it’s the first fake burger to satisfy my burger craving, and none of the others come close. Maybe if I were still eating real burgers I’d know what I was missing.

I thought it tasted like beef, but like a cheap, lean beef. Like the cheap, premade, frozen patties you can get at the grocery store. Not a bad flavor at all. Just mediocre for a burger.

I've had it several times. It's not going to be the best burger you've ever had, but it is quite delicious and leagues above the standard veggie burger.

I tried the Impossible burger @ Umami Palo Alto. I was quite impressed, it tastes like a real beef burger and not like a vegan burger thing.
