The burger is good but not astoundingly good (unlike Carl's Jr). But then burgers here are fried and at Carl's Jr grilled so maybe they're not worth the comparison.
Anyhow I appreciate the plain beef patty not being flavorful, for the lack of sodium. Apart from that, I think the burgers compete alright.
What's astoundingly good here is their fries (both flavors). They taste like real and freshly chopped potatoes.
