I'm also going to review momokawa soon, which also serves shabu shabu, but to answer your question i didn't find a big difference between the two for shabu shabu. however, the upside to momokawa is some of their other food is quite good
those are the only places i know of that really serve it now that lan is gone (there is one on the UES, but i thought it was pretty crappy)
I have found none in the city or neighboring boroughs.
Perhaps it is not cost effective versus prices most people want to pay.
If you are a purist and want great broth .. Try 小肥羊 on Main Street near Northern blvd in Flushing.
No ambiance but the broth is worth the trek and you can order live Alaskan king crab .. but be wiling to spend if you order all seafood ..
Most diners savor a bowl of broth before they start ordering .. They will replenish gratis!
We actually tried this place a few times this year :)
Our friends are carnivores lol and they enjoyed this place!
We prefer elaborate seafood selections, so the menu choices were quite limited for us.
Despite that, the prime rib-eye we had chosen was sliced perfectly for the quick swish in the bubbling broth.
