"The restaurant was closed, but the factory was still operating. You’ll need to go around the corner to find the back entrance. I picked up a bottle of sweet soy milk—I had hoped for the unsweetened version, but it was sold out. I also tried the fried dough (油條), which were the most authentic I've ever tasted in the U.S. The soy milk was rich in soy flavor, indicating it was made from real soybeans rather than being reconstituted from soy powder. The fried dough was crispy and just the right amount of greasy. Just a heads up: they only accept cash."
