I go to HK/Macau/China every year for work so I have some experience to work from. As a matter of fact I just came back on Monday from a work/wedding trip there.
Over the years I've eaten at all types of restaurants, and from HK to Kowloon to New Territories. On average, the food in Vancouver is cheaper, fresher, and better. Not to mention we have WAY BETTER service. I would say, unless you're willing to drop $1000+ HKD a person, you're not really experiencing anything better. On the low end, there's plenty of cheap food in HK so that's also a plus. Just remember to bring Tempo paper and be prepared to share tables.
The two things I suggest for decent prices:
1) Buffet at a nice hotel. I'd recommend the one at the JW Marriott at Admiralty or The Grand Buffet at Hopewell Center in Wan Chai (there's also a location at Grand Lisboa in Macau). Imagine a Vegas buffet but with plenty of seafood and Chinese delicacies. The one at Marriott had Fish Maw and whole lobster, the Grand Buffet had Roasted Suckling Pig and other seafood.
2) Dinner at Dai Pai Dong. I usually go to the one at North Point or Happy Valley and you can eat at the wet market. Think of it as between a very run down Parker Place Food Court or a very glorified Hawker Center. Plenty of seafood and other stuff that has a lot of "wok hey". Definitely something that we don't really have here.
Having said that, I had to chance to go to Macau and have some food there. They have plenty of places that serve cheap shark fin and other seafood so it's definitely a try. I'd venture to say Macau has a bit more culture to the food and environment once you get away from the casinos. I loaded up at Koi Kei Bakery since it's famous and plentiful but I just saw the same stuff for sale at T&T last night
