I’d say they are hit and miss in general. The dishes themselves are good. They are Vietnamese trieu chau (teochew) dishes so perhaps a different take on traditional teochew dishes. The noodle soups include thin sliced pork, thin sliced chicken, minced pork, a regular meatball, a meatball with tendon, and two shrimp. They offer the option of additional won tons. The bowl is garnished with crispy fried pork lardons and sometimes a touch of fried garlic. Noodles are your choice of flat soft rice noodles or thin yellow egg noodles served in a pork broth. There are other dishes like fried radish cake, beef stew, duck noodles, etc. So the dishes themselves are good but I can’t vouch for the recipe and consistency of each place.
I recently had a bowl at New Tung Kee (or was it TK Noodle?) in Gilroy and enjoyed it. It was only $6.25. I like getting half rice noodle and half egg noodle for the textural and taste contrast.
