D.C. area restaurateurs hit Philly to probe the secret to the perfect cheesesteak roll.
Taylor Gourmet's David Mazza, left, and Casey Patten test the cheesesteaks at Steve's Prince of Steaks in Philadelphia. With their baker, Alan Hakimi, Mazza and Patten scouted several Philadelphia cheesesteak establishments in search of the finest bread so that Hakimi can try to reproduce it. Mazza and Patten plan to open their own cheesesteak restaurant in D.C. this year. Ricky Carioti/WASHINGTON POST Buy Photo
