We come here pretty regularly for lunch just because it's a rather convenient location from where our offices are. Everyone can get here easily, there's usually no problem parking, and food arrives fairly quickly.
I normally get the baked dishes here, like the baked pork with rice, which I think is really good. Great portion size for me (left overs for tomorrow!) and good taste. There's just enough acidity in the sauce to keep it from being bland, and it's not too salty. I've tried other dishes as well. The Hainese Chicken with rice is a great one here. If you want it for dinner, you can call early and ask them to save one for you.
It's a bit more pricey than regular HK Cafe and less options (which isn't always a bad thing considering that you wouldn't want a kitchen that does a bunch of dishes mediocre). I think that for lunch, this is a good spot. For dinner, I think it's over priced.
Service is good here. Staff are usually quite nice and efficient.
I think we come here more out of convenience and we all have the 1 or 2 dishes we just keep ordering every time. But given more time, I don't know if this would really be our go to spot. Still, give it a try. It's a good place to go :)
