Man cannot live on pig intestines alone. And on those nights when you crave something comfortingly familiar yet still vaguely ethnic, Imperial Chinese Restaurant fits the bill. Although the dining room here is red-dragon-and-white-tablecloth elegant, it attracts a casual crowd of diners looking for the kind of tame, sterile thrills that only Chinese food done Colorado-style can offer. Which means all of the American-Chinese favorites, executed in exemplary fashion: sesame chicken, sweet-and-sour shrimp, Peking duck and fried wontons (filled with ground pork, not eels or anything weird), and fortune cookies that deliver only good news.
