The specialties here are corned beef, hot pastrami and kosher hot dogs. Loyal patrons line up early for lunch, so be prepared to wait at least 10-15 minutes for your order. To avoid the crowds, stop by before 11a or after 2p. Free parking is available across the street. In business for more than 75 years, Attman's is perhaps the oldest deli in Maryland, and one of the best-known Jewish-style delis around. Both John F. Kennedy and Jimmy Carter ate here. Attman's also offers catering services.
