I don't like restaurant potstickers nearly as much as homemade! Although, depending on the sauce I dip it in, it can be good enough to eat 2 or 3 at a buffet (compared to a half dozen or more at once if homemade!) The outside is a sort of wonton skin, which when we make it, isn't crispy (except maybe right at the tips if it's overdone) but is sort of soft, and inside is ground pork and maybe some other flavor ingredients like chopped up water chestnut, green onions, ooooh, and chinese mushrooms which gives it a good flavor. And they can be made in (usually) two basic shapes:
The half-moon shape, which my mom prefers, and a sort of sticking up lotus flower shape, which is harder to get it to stay like that when you cook it. *hunts for pics*


(Oh, the bottom can be sort of crispy too sometimes! As seen above)

(although like seen here, they're usually soft, and sometimes shiny!)
(sometimes called 'dumplings' too, as in the neoimage)

Oh! Here are the wrappers/skins

Argh! I can't find images of the round, standing-up ones.
