Which dish combines beef with a unique Beijing-style preparation?

The dish that combines beef with a unique Beijing-style preparation is Beijing Beef. This dish features tender pieces of beef that are stir-fried with vegetables and tossed in a flavorful sauce inspired by traditional Beijing cuisine. It showcases a style that emphasizes sweet and savory flavors, along with a slight tanginess that makes it distinctively Beijing.

Beijing Beef is specifically designed to evoke the culinary traditions of Beijing, reflecting cooking methods and flavor profiles that are characteristic of that region. This includes the use of sauces and spices pertinent to Beijing-style dishes, which sets it apart from other beef dishes on the menu.

In contrast, Broccoli Beef focuses on the combination of beef and broccoli in a soy-based sauce, while Orange Chicken features chicken that's sweet and tangy due to its sauce, thus not aligning with the particular style referenced in the question. Shanghai Angus Steak is another distinct dish that highlights Angus beef but is more associated with Shanghai's cooking style rather than that of Beijing.
