I waited a year and a half to go to Farrens, which was a huge mistake. The burgers are great, and probably the best ones in the CU area (though I still have lots to try). But what really sets the place head and shoulders above everyone are the potato chips with truffle salt. That stuff is fantastic, and totally worth every extra penny.
Beer selection is okay, and they rotate stuff throughout the year. Staff is also very nice. Farrens only gets four stars because the bar selection isn't the best and because the decor feels a bit run-down. Still an excellent place to go.
