Meh. I'm not sure why people so desperately want to make this place cool. The burgers are very mediocre. They don't taste much better than (and are quite similar to) the burgers at the fast food chain Steak & Shake.
I hit up the midtown location in NYC and was underwhelmed.
Tried it again here in Vegas at New York, New York and, again, was not impressed.
I'd give this place like 2.75 out of 5 stars.
Fukuburger across the street is MUCH better! Hell, In-n-Out has a location a short drive (a mile, maybe) away.
