I just want to note that I'm completely obsessed with Ah Ping Snack Bar, the place that's finally made me fall in love with Foo-Chow food. I go again and again....haven't had a monogamous relationship like this with a Chinatown place since beloved Shing Kee closed down in the early 90's. Maybe New Green Bo for a while in the meantime, but even that wasn't steady.
Other chowhound posters have praised their peanut noodles. I think that's actually the only off dish (still decent, though). Get the loofah soup (with tiny clams and subtle, loving broth), the meat-stuffed gelatinous rice balls suspended in liquid ("Meat Stuffed Rice Flour Ball Soup"). Rabbit, clams, or, best of all, intestine in fouzhou sauce (a wine sauce). Lamb in wine dregs. God...the razor clam omelette. Water spinach in fermented bean curd sauce ("foo yee" in cantonese, "foo roo" here, in mandarin). Many many other extraordinary things, almost everything served with cauliflower. The chef is for some reason obsessed with cauliflower.
Very barebones, sit on stools at one of the three tables. Only water to drink. No English spoken.

Note: the waiters are really anxious about getting orders right....please don't just point at the dish, block out the calligraphs between two napkins (one above, one below) to stave off Server Stress.
