I don't have the list memorized but there are some dishes at Joy restaurant's (Foster City) Chinese menu where you need to reserve select dishes in advance to order them. I remember have two such dishes in the past 2 years and they were superb.
First one was the "foo gwei gi" or what is dubbed "rich chicken". Basically the same deal as "beggar's chicken" (beggar doesn't sound like a good dish name for dinner!) hence the name change where the whole bird is stuffed with various ingredients (Joy uses sticky rice and seasonings), plastered with mud and baked in the oven until the meat falls off the bone. They stamp it with a Chinese character (forgot which one it was) and right before serving they bring the bowling ball sized thing to your table and smash it with a hammer to remove the hardened clay layer. I remember this being fantastic and as I haven't had the real deal in a long long time, I have nothing to compare this with. $29 or so I recall.
The 2nd advance order dish I had was something called shao ti, which is essentially boiled/steamed pork hock. This was $16 and deifnitely a healthier and lighter alternative to yuan ti (the stewed pork with a lot of fat, thick soy based sauce, usually served with veggies) which has a lot more fat. The shao ti appears to be have marinated in brine before boiling and was the softest and tastiest side of pork I've had, even rivaling or surpassing good German's pigs knuckles.
Pretty soon I'll be trying their version of "8 treasures duck". Has anyone had this recently?
Please chime in if you've tried anything else of theirs that requires advance ordering. I'm wondering if there are any other specials worth ordering! I don't even recall if shao ti was on their Chinese menu. It was the best dish that evening...made the regular items seem not tasty at all :-).
