If it's your first time at Protzel's in Clayton, you pretty much have to order the corned beef, made in-house and piled high on rye bread and covered with mustard -- served, of course, with a pickle. Since 1954 this family-owned establishment has been churning out a wide array of fresh deli meats and cheeses. Other than the corned beef, you can also try the knishes, potato salad, deviled eggs or fresh Jewish rye bread chips. Or shop around for European goodies, taffy and sweets -- three entire shelves are devoted to mustard! The full selection of sandwiches at Protzel's includes roast beef, pastrami, peppered beef, salami and bologna. The deli also offers specialty sandwiches, such as the "John Carney Special," with a third of a pound of corned beef and pastrami, Munchee cheese, honey mustard and coleslaw served on an onion roll.
