One word: delivery. Unlike every other restaurant of any sort in San Francisco, they deliver. You do have to talk to a rather brusque lady though. As for the food, there are some really good choices. The thrice cooked bacon is pretty unique and interesting, and the Westlake porridge regularly delivers subtle flavors. The salt cod fried rice, when they get it right, also has great contrasts in texture and flavors. I've had some misses though, Last time I ordered from there (so, last Thursday), the forbidden fried rice was a disappointment - bland, and the texture of the forbidden rice (which as more bite than regular short grained rice) simply didn't work as a fried rice.
I make sure to get it once every time I am in San Francisco. It makes for a nice meal when you've been working all day and you go back to your hotel. No, it doesn't live up to the hype. "Most important new restaurant?" C'mon now. But it's an interesting take on Szechuan food (from what little I know of that region's food, far from "authentic"), and it's reasonably priced. And so it gets a plus in my books.
