Taste of China - always my spot for eats in Chinatown, late-night or otherwise.
I first went after cornering a Chinese-Canadian friend who's also a chef and straight up asking him where he eats in Chinatown. Taste of China was the answer.
The food quality is solid. I've eaten there a lot and everything has been up to snuff. But don't take it from me. Take it from the big table with the lazy susan surrounded by staff and servers from other local Chinese restaurants, in their white shirts and black slacks, choosing to eat here after their shifts instead of their own restaurants. Take it from the Susur Lee sightings (he's a cusser I here). This is the place to go,
And they have clean washrooms. Super clean washrooms. I've gone to too many well-reviewed little restaurants only to be turned off by a filthy washroom and thoughts of what the kitchen looks like. Not here.
Go where the pros go. Go to Taste of China.
