I have gone to Fat Wong's. It's ok. 3 to 3.5 star sounds about right. Not the greatest but not poor by any means. I liken it to a tapas place in that you can order smallish dishes as opposed to say eating family style at a full menu'd chinese place. My understanding is that these type of places flourish in HK. I get the allure. This would be an ideal place (if opened) for late night snacking after say a movie or clubbing. Light dining.
I have not gone to Dragon Beaux, but do want to. It looks fine, but I do tend to stay away from the Richmond in general due to the parking.
You and Ms. Harriet may be thinking, oh come on, he doesn't do chicken feet and he is first generation (so probably likes PF Chang's). Wrong. Yes, I don't do chicken feet but I actually love chinese food the most and prefer it but I do have a Malaysian wife who likes many kinds of foods. To prove my preference, I had to have my wedding rehearsal dinner in Chinatown in my favorite hole in a wall place. It is not a great place by any means but the place means a lot to me because this is where I was born and raised. I didn't care about my snooty NY cousins who probably panned the place (I made up for it next day with a full blown wedding at the St Francis Yacht Club). This is probably something along the lines of your place, it is a place frequented by local chinese people. Fairly cheap and it is darn authentic. I love getting the snails when it is in season.
