Last night we stumbled into a basement restaurant in Chinatown -- New Woey Loy Goey Restaurant.
Looks like it has been there for a very long time.
I see only one or two mentions here on chowhound, both several years old.
I asked if they had any specialties, and the waiter pointed to the fish tank and said they did crab or lobster with a black bean sauce (or alternatively, I believe, ginger scallion). I asked if the black bean was the traditional cantonese sauce for lobster, and he said yes. So I decided to try the lobster cantonese.
This was my favorite dish as a child (only for special occasions, as it was expensive!), but I have not had it in a long time (decades!)
I've never tried it before anywhere in SF, so I have no idea whether I lucked out or whether other places in SF are this good. But this was absolutely amazing. One of my favorite things ever. The sauce had black beans, ginger, ground pork, chunks of onion and chunks of green pepper. It was amazingly flavorful, and the lobster was perfectly cooked and delicious. This was quite different from the more bland 1970s east coast counterpart that I remembered. But I have to say, even with the nostalgia factor, this was much better even than the dish I remember from my youth.
I am craving it again already and can't wait to go back.
Warning! It's pricey but IMO worth it. They charge $18 a pound, and mine showed up as $27 on the bill, so I guess it was a 1 1/2 pound lobster which sounds right for what I received.
Also, when the bill came it looked a bit high. The dishes added up right but the writing below that was cramped and messy. So I asked if the tip had been included, which would have made the grand total add up about right, and our waiter said yes, tip was already included. So watch out for this or you may end up double-tipping...
