I have been to Farren's about 10 times and I'd say their burgers are the most delicious in CU area. The quality of meat and how it's cooked is near perfect. The highlight is the blue cheese sauce in the Russel. For blue cheese lovers, it's that great especially with the sauteed mushroom. The fire burger with blue cheese sauce and ghost pepper cheese was one of the things to die for after the Russel. The service is usually quick and friendly even though the line is so long.
