I know this is not in Durham, but the Corner Bar in Cary has 10oz burgers served rare to well done, ground in house, on a pretzel roll! My favorite is the avocado, grilled onions, and cilantro mayo burger...never eaten mayo before until here! Also, all their appetizers are made in house from scratch, even the Loaded tater tots! Also, I like City Beverage for their tres bien burger with veal demi, and gruyere! I want to try Watts soon.
