I'm new to the area, my SO is flying in this weekend, and we would like to try shabu shabu for the first time. Several names keep coming up (Koji's, Kagaya, Zakuro) and wanted to know others' recommendations. We would like a "nicer" place, but is Kagaya that much more expensive (i.e. worth it?) than the others? Also, I actually live in the wasteland that is Riverside, so if there are rec's that are closer, that's great too.
