Donghuamen night market is pure tourist trap. Overpriced scorpions on sticks and terrible jianbing that costs 3x normal price.

Better options for street food include gui jie ghost street for proper late night eating. If you must do touristy food markets, wangfujing snack street has marginally better food quality than donghuamen (though still overpriced and instagram-focused). Locals dont go anywhere near donghuamen, and honestly most avoid the main wangfujing area too.
