We can't say we exactly miss the American-Chinese takeout dishes that defined this country's perception of Chinese cooking for at least a generation — it's hard to go back to mu shu when you've had real Beijing duck, and wonton soup is much less interesting than fiery Sichuan dumplings (or chao shou). That said, we do occasionally feel nostalgic for the egg drop soup, sesame chicken and General Tsos of a different era. When we get that feeling, we head to Peter's, which has been serving the metro area well-executed versions of American-Chinese classics since the '80s. Highlights here include the shatter-crisp sesame chicken, sticky with caramelization, and the thick-set, burnished scallion pancake, served with a savory ginger-soy dipping sauce. Go at lunch, and your meal comes with fried rice and a delicate egg roll, sided with sweet-and-sour sauce and hot mustard.
