5 stars for the food - because it's great for its price point. A truly authentic experience, as recommended by my Cantonese friends. The brusque/slightly-yelling service, limited menu options, and bare decor = feels exactly like Asia. Service is fast but you need to make an effort, this is not a fine dining experience where they'll wait on you.
Come here only for the wonton noodles, I'd recommend them with shrimp dumplings.
