"Buster" or "bust" is slang for "eliminator" or "eliminate". Here, he is saying that Chinese takeout "eliminates" hunger by being a convenient and quick meal. "Buster" is a somewhat common expression. Ex: This new video game is a boredom buster for all ages. Ex: Bust summer heat with a portable fan.
