@Grivusangel -- Sometimes I mix egg drop and hot and sour soup. Cuts down on the sour, but you still get some heat, which is good.
My favorite thing to do if I'm at a buffet is to get a bowl of hot and sour soup and spoon a wonton from the wonton soup into the bowl. It adds some meatiness to the soup. My friend who owns the local Chinese place tells me that's her favorite lunch when she's working: a big bowl of hot and sour soup with three or four of the wontons.
