Roaring Fork chef Robert McGrath has achieved something we didn't think possible, something long sought after by cooks high and low, the Holy Grail of American grilling, if you will. That is, he's built a better burger. That's a 12-ounce Big Ass Burger, to be exact, one that you can only enjoy during dinner hours in the saloon area of his popular Scottsdale restaurant. We know what you're thinking: All hamburgers are pretty much alike. And so we thought until we saddled up to the bar at McGrath's Southwestern-themed establishment, and bit into that ground hunk of primo cow flesh, topped with roasted green chiles, longhorn cheese, grilled onion and bacon. Eaten medium rare, with a glass of Pinot Noir as accompaniment, there's no better way to massage the pleasure centers of your brain, unless of course you happen to have a bikini-less Lindsay Lohan waiting for you in a Jacuzzi somewhere (or a Speedo-less Jake Gyllenhaal, depending on your preference). In which case, we strongly suggest that you eat McGrath's piéce de rèsistance as quickly as possible. Readers' Choice: Fuddrucker's
