Very disappointed.
I've heard my co-workers raving about this place and this just doesn't compare to any of the raved "gourmet" burgers I've had. Not In'N'out, and definitely not Shake Shack quality.
The patty was meh. Where is all the juice?
The traditional egg bun is interesting, but not roasted. A $5 burger should have their buns ROASTED.
The smash sauce is gross.
Just don't go there for their burgers.
