If you want authentic Hong Kong-style food in Dallas, Royal China is one of the top picks for dim sum and Cantonese dishes. Garden Restaurant in Garland is popular for classic Hong Kong café (cha chaan teng) vibes with baked rice, milk tea, and noodles. First Chinese BBQ is great if you like roasted meats like char siu and duck. I’ve also seen people recommend Kirin Court for dim sum if you don’t mind a busier spot on weekends. It really depends if you want traditional Cantonese food or more of the Hong Kong café-style experience.
