4.5 stars. Great burgers, nice beer list, nice ambiance. Be aware that when you order medium rare, you are going to get REAL medium rare, not the "medium rare" that we've all grown accustomed to ordering to get a bit of pink in the middle. My burger was juicy - incredibly meaty-tasting and generously portioned. Loved the sweet potato fries and the beer. A definite win at Vegas...
