Review for Del Mar Fairgrounds Review For O'Briens Google User Mar 12 '18 at 2:58 Sandwiches here are so good! The variety of breads to choose from is really what sets these guys apart. All their breads are super fresh and you can choose anything from a croissant, french rolls, Dutch crunch, rye, white wheat, sourdough, and my favorite the pumpernickel swirl. They have this sweet dill mustard that is so good I ask for extra on both sides of the bread. Hidden out in Escondido in an industrial area but easy to find. View full site to comment or like
