I tried it yesterday. I didn't think it was bad. I would say it's closer to a tender than a patty. To me, a patty is a more uniform size and is pretty heavily processed. The chicken itself was moist and not overcooked. The top bun was toasted well, but the bottom bun didn't hold any of its crunch because of the amount of butter used. Both top and bottom bun were drenched in butter, which isn't necessarily a bad thing, but it definitely overpowered the rest of the sandwich and was pretty heavy for a hot day at the park.
If it was seasoned the same way, there wasn't nearly as much as the tenders. It also didn't have as thick of a breading on it. I think it could have done with more seasoning (or less butter on the buns)
Would I order it again? Probably. Would it be my first choice in the park? Probably not.
