Adding to my post from above, they also really screwed up our order. My husband had asked for no cheese, sauce on the side. They ended up not putting cheese on either order, but did put sauce on both orders. Plus, it took a fairly long time for the orders to arrive.
And this is also when we found out they don't do Freestyle Coke unless you have a souvenir mug... which kinda really screws over all the AP folks, who may only stop into the park for an hour or so on a given visit. Unless they start making a season pass refillable mug, which is something I do think they should work on seeing as they're the only major park that offers a refillable option for guests, but doesn't have a seasonal version of it. For goodness sake, even Six Flags managed this years ago.
I'll probably give it another try later, but my husband preferred Bumblebee Truck's tacos. And while it wasn't great, it was better than just more burgers, so it's still a slight improvement.
Oh, and just to clarify, even though I said I got the beef tacos, I did get the Impossible option.
