The equation is perfect. Take the Foundry's patio, add the wooden stools firmly placed in the gravel, add some hair of the dog and multiply that by a biscuit sandwich the size of Giada De Laurentis' head. On the other side of the equation? A future nap and a dead hangover. Go for the restaurant's namesake sandwiches: The Foundry has fried chicken, collard greens, an over-easy egg and Tejano red sauce. You may need a cab ride home or a neck pillow to finish this sucker.
