Corned beef on rye with a pickle. It's really the only thing you need to order at Protzel's Delicatessen. Five days a week if you want to -- and why wouldn't you want to, seeing as how it's made fresh every day? Maybe even for breakfast; hell, the place opens at 7:30 a.m. But those who prefer a little more variety needn't worry. Since 1954 this family-owned establishment has been serving a wide array of fresh deli meats and cheeses. Rather than the corned beef (did we mention it's made fresh daily?), you might try the knishes, potato salad, deviled eggs or fresh Jewish rye-bread chips. You could also cruise the joint for European goodies, taffy and sweets -- three entire shelves are devoted to mustard! If you're lucky, you might snag one of the two tables outside on a lovely, tree-lined stretch of Wydown Boulevard in Clayton. Protzel's offers seven-days-a-week catering services, but bear in mind that the deli itself is closed on Mondays.
