My favorite vietnamese place was similar, restaurants had been in and out of this location, didn't look good. But it was run by a vietnamese couple - husband did ALL the cooking and wife did ALL the waitress,hosting,etc. It was in West Palm Beach when I lived there, and we went 1-3 times a week for almost a year. I bet I barely missed a week. The amazing thing is their menu wasn't huge, we only ordered ~5 dishes in rotation but they were just so good it didn't get old at all. Spring rolls( non-fried, fresh, rolls that is) are one of the best ways to start a meal.
