"Sam LaGrassa’s claims to be home to “the world’s number one sandwiches.” We checked with the UN, and it turns out that ranking culturally important sandwiches isn’t something they do, so we can’t completely verify that. But what we can tell you, is that the giant pastrami travelers sandwich on pumpernickel is pretty close to perfect. This old school deli is only open for lunch and it gets very, very busy, but you can order ahead and you should, because eating these meaty sandwiches on the Common is close to an ideal Boston lunch experience." - dan secatore
