My favourite is this food court place in Richmond at Empire Center -- Cloud 9 Delicacy / 雲頂閩南美食. It is supposedly a Taiwanese place, but the store keeper lady speaks Canto as well (in addition to Mando, and I would expect her to be able to speak English too).
And this is the reason why the place has become my current favourite -- $15 a dish of the above.
They are quite a busy stall, and I would definitely recommend against going during the normal lunch rush. One time I got there on a Sunday slightly after 12pm, and I ended up waiting ~25 min for the popcorn chicken dish. When I go there between 11 - 11:30, the wait time is quite reasonable.
The popcorn chicken is always piping hot when it comes out, and is excellently flavoured -- one of the best I can find in Vancouver, I'd say. The meal is served with 4 side dishes -- marinated hard boiled egg, nappa veggie, (Taiwanese style?) pickle, marinated dried tofu, with rice served in a separate container. The boss lady will give you a paper cup for some self-served tea as well. The portions are very generous, and is enough for 2 people to finish as a normal meal. But if I am feeling hungry, I can totally wolf it all down on my own.
The deep fried porkchop dish is also well flavoured. They typically give 4 large pieces of (bone-in) porkchops.
They also have a deep fried chicken breast option as well, but I never order that since I like popcorn chicken better.
Parking at the plaza is your typical Richmond affair -- that is to say, it is absolute dog shxt, both at the surface lot, as well as the multi-level parkade.
The food court there also has a number of other top notch food stalls, but because of that, the seating there is inadequate for the number of people eating there.
TL;DL
yummy, very generous portions, $15/dish
