I've been coming here for over ten years and have yet to leave disappointed. I've been to other Hakka places that are much closer to my house than Federick's and they're not as good!
Don't come here if you like using anything besides a fork to eat your food. Also, food comes out at it's ready so you end up finishing plates before others come out. Staff isn't really friendly or attentive. But who cares when the food is good, right?
Kan Shue green beans are exceptional. Chili chicken and curry chicken are really good. Mee goreng is also great.
It seems like some reviewers didn't like their food. Perhaps newcomers should read yelp reviews before going so that they make sure they order the best items?
