3 Brothers From China is one of the few "real" Cantonese Chinese restaurants in Contra Costa. They serve up standard American style Chinese food but also have a separate Chinese language menu where you can get the good stuff! The restaurant is popular with asian families in the neighborhood, and it's usually packed on Chinese New Year.
The Chinese menu has a variety of dishes to choose from, all at lower prices than the other menu. They usually serve a traditional herbal soup along with your choice of entrées, and dessert. My favorites are the cold jellyfish appetizer, the claypot dishes, stuffed tofu, and stir-fried long beans. Nice steamed fish too.
