years. But I've gone twice in the last couple of months and it's been pretty good both times.
Those first few times, it was an insane wait, dirty tables (and in one case, no tables at all so we had to eat in the car), and the burger was a solid meh - not bad, but certainly not as good as everybody hyped them up as. But definitely not worth all the negatives.
I went like 2 weeks ago, the tables were clean, the burgers were fast, it was a pretty good value. I didn't even mind the fries.
