I use them, too, but the Japanese style, which are strongly tapered. (I think that's fairly exclusive to Japan and would appreciate the correction if wrong.) And we use them at home very often.
Of interest, perhaps, is that the Japanese are the only culture I know of who use chopsticks exclusively (no spoons, etc.), unlike other Eastern cultures.
As far as food is concerned, there is a huge world far beyond sushi that everyone should explore, given the chance! I can't recall a single Eastern or Indonesian food I didn't enjoy.
