Cousin Tida, Kwong's is a much different experience than HK Flower Lounge. But I think it's equally satisfying when you take price into account, and no one makes better fried oysters than Kwong's. I mean, just look at the two buildings. HK Flower Lounge is a gilded temple to Cantonese dining and Kwong's is just another neighborhood place from the outside. But the trouble is, the service at HKFL has gotten stiffer and more impersonal, the more creative dishes can sing but are inconsistent, the tables are crammed tighter together, garage and valet parking are a hassle, reservations are needed most times, and prices are higher than the value received, all things considered.
For special family gatherings, we've abandoned HKFL in favor of Fook Yuen and Seafood Harbor. For dim sum, I think we end up at Seafood Harbor more than the others because we love the fried taro root ball and the soup dumplings so much. When my brother's car was stolen with his checkbook and credit card bills in it (which suspended his ATM and credit cards when he reported it), I had to take him to pick-up a rental car on one of my cards. With no lunch money, he was pretty hungry when I arrived and I told him I'd take him anywhere he wanted for lunch. He picked dim sum at Seafood Harbor.
Kwong's is the place for a solid Cantonese dinner at an every day price that performs above its price point. As I mentioned before, I haven't had much luck with the specials. I'm always curious about the items in Chinese characters (with prices in $XX.OO indicated clearly) and have the waiter read them to me. They sound good, we order them, and usually we prefer our old reliables over the specials.
R&G Lounge in SF is the opposite. They don't do a consistent job on the standards and you need to know their strengths to get a satisfactory meal. Link to favorites below, and if you click up the thread a couple messages, you'll see that I'd had a similar impression to yours initially.
