Our Story我們的故事

A Taste of Home

家的味道

Tasty Box started with a simple idea: bring the authentic flavors of a Hong Kong cha chaan teng to Diamond Bar. No shortcuts, no fusion experiments — just the dishes we grew up with, made the way they should be.

From our hand-pulled wonton noodles to the slow-roasted char siu glazed over charcoal, every dish carries the same care you'd find in a Mong Kok side street.

What Our Guests Say

客人評價

The char siu here is the best I've had outside of Hong Kong. Perfectly caramelized, tender, and that honey glaze is unreal.

Regular since 2023

My family orders from here every weekend. The dim sum is always fresh and the portions are incredibly generous.

Finally, proper HK milk tea in the SGV. Rich, smooth, not too sweet. Takes me right back to Tsim Sha Tsui.
