The burgers are *really* good. The reason I've given them four rather than five stars, however, is that nearly every time I've gone they've gotten something wrong. It's usually the temp of the burger - I like mine really rare - but it is also often the toppings, which is kind of a bummer when you build your own. Regardless, even if to me it wasn't perfect, everything I've ordered there has been tasty.
(Pro tip: sure, the burgers are good but the chili is wonderful and the nachos are among the best I've ever had. Get the nachos.)
The cocktails are really good (especially that grape/basil thing they have going), but the wine list is and has been terrible. The beer selection is also good, and changes frequently.
As for the service, it's what you would expect from a hot spot. The men are aloof and the women bitchy. Ignore them. Eat nachos.
