"What’s better than an American-style diner serving an excellent club sandwich with crispy bacon, golden brown fries, and a thick chocolate milkshake? How about a Mexican twist, featuring enchiladas and aguas frescas on the menu? Klein’s has perfected this formula since the opening of its first location in 1962 by a Texan cadet and his wife from Puebla. There are dollar pancakes and a secret family recipe for mole poblano—dense with a spicy finish—along with other Mexican specialties that locals can’t live without. Because the place was established and has thrived in Polanco, a neighborhood historically associated with the Jewish community, they also offer kosher dishes, like a chicken noodle soup that’ll lift your spirits on rainy days." - mariana camacho
