Going incognito in a baseball cap and black sunglasses, the Mad Men star popped into Lansky's Jewish Deli, where he ordered a big bowl of matzo ball soup.
"He was quiet throughout his meal, but was very polite," an onlooker tells PEOPLE, adding that Hamm read the newspaper while dining. "He walked into Lansky's and knew exactly where he wanted to sit and what he wanted to eat."
