"Mam, home to the city’s “most exciting Vietnamese food,” is the definition of no frills: The food — flavorful pho, fried chicken tendon — is delicious, but you might eat it on a small plastic stool on the floor of a hallway turned into a makeshift dining room. Don’t be dissuaded by the website, which allows patrons to order in advance: It’s possible to walk in here without a reservation and order in person." - Eater Staff
