Hi ED-209,
For overall experience and quality of food, KaGaYa ranks as my #1 favorite. However, I still like to go to Mr. Shabu Shabu on weekday night as it's in my neighborhood and Swish Shabu on weekend night as it's located at my 2nd home

. During the last trip to Mizu 212, food wasn't as good as I remembered... however I learnt that I have to ask for the 'shiu may' (aka. dumpling) on my vegetable plate while placing the order. If not, 'shiu may' becomes a side order
I heard that Kushi Shabu Shabu in Little Tokyo, CA offers good shabu shabu too. Hopefully I get to try this place soon.
Regards,
ATM
