I'm not saying don't go. You should just go in and try it with no real expectations. I went there once, tried some off another friend's and was like "umm...okay? What's so great about this place?"
I feel that they overdo everything, especially in the taste/flavour department. Every bit of sauce or condiment or what have you is just "BLAM!" here you go kinda thing. I'm not expecting a 3-star Michelin dining experience but the hype and glorification of this hipster circle jerk does not deserve the credit it is given. If you partied last night, have a hangover still and have the munchies, yeah, by all means, it'll be a 10/10 A++ will return experience.
And I'm sure it's a joke but they have a list of 10 rules at the diner and the first one is "Ketchup goes with everything, including pasta." I'm not sure that it's my kind of place to hit up. Just sayin'.
Give it a go and let us how it went.
