tldr; avoid, great build your burger options marred by inconsistency. Burgers are overcooked, waitresses are disinterested.
Oh boy, this place. I was pretty excited when it first opened but I literally reopened my Yelp account just to leave a review.
I'm going to start with the sides since they matter the least. The fries are decent enough, sometimes they salt them a little too much. Onion rings are great and potato skins are bland but complemented VERY strongly by the sauce they top them with (so the bottom of the pile where you run out of sauce is kind of lame). I recommend sharing the menage a trois, it's good enough to feed 3 even 4 if you're not a heavy eater and you get to sample everything.
They say they cook their burgers pink. In fact, it seems like a point of pride for them. Too bad, in my 6 times here, they've never been cooked pink. 5/6 times, my burger has been overdone and dry. They don't really season the patties too much so you'd hope for a juicy burger to make up for that but it doesn't work. The only time my burger wasn't well done, it was medium well (nice job guys!!). I'm also not a fan of the lettuce they use since they put too much, it adds a lot of crunch but it also seems to overpower the rest of the burger. It also adds a ridiculous amount of height. I usually build my own or get the divine inspiration which is a discount big Mac. Again, the inconsistency as far as toppings go do not maintain a consistent flavour profile. You want a good burger on crescent, go to burger bar. They don't cook it pink (I think medium well) but the patties are well seasoned and they will on request.
Service is also not very good. The waitresses are terrible. I had a waiter once who was really chill and who cracked jokes but otherwise, they're kind of cold, or unattentive. Cold is a little bit of a harsh word but I'm trying to imply that they don't seem to care.
So there's that, not sure if the original restaurant is better, I'm sure it is. This place has huge inconsistency issues. The only appeal to me is that our can build your own burgers, but you can "unofficially" do that in burger bar.
