Overall:
The best quick-Chinese (Hong Kong style) food I've ever experience to date.
Personally, I like the wonton-noodle (dry or soup) the best. Nice textured wonton skin with fragrant filling; I haven't found any other Chinese restaurant that has done wonton this good so far in Perth (if you do, please let me know!).
If you're sharing with friends (which I highly recommend), roast duck (or pork, depends on your liking), wonton soup (don't forget to ask extra veggies, good for you!) and sizzling seafood will go really well with rice. All noodles dishes are very well done too, as long you don't mind the 'fattening' factor, as any other typical Chinese stir-fry noodle :).
This restaurant is naturally my first choice for a quick meal (i.e. lunch), especially I work in the city centre of Perth. For $10-$20, you can get a great meal with a beer too (what a deal)!
When I say 'quick', it's simply because it's not the type of restaurant where you want to have a 'romantic' dinner out (NOT saying that you can't :)), but for the price you're paying, it's certainly has an excellent ambience and service quality.
If I'm a tourist, this restaurant will be on my top-3 list, as they have so many great choices (5-visit a week, no worries!) with great value for money!
PS: I tried the one in Victoria Park branch; they have the same quality of food.
