One of my favorite things to eat is shabu shabu and having lived in Los Angeles for a large majority of my life, and have lived in Sawtelle Japantown, I've had it innumerable times.
The ambience of Ushabu and the service were amazing.
However, the shabu shabu was less than impressive. There was not the usual plentiful quantity of veggies and this left me incredibly hungry and for a price tag of $27 it was definitely not worth it. I got the beef and the quality of the meat was not good; there was fibrous connnective tissue in the meat that was unpleasant to chew. The sauces were in tiny bowls which was difficult to dip the food in and they didn't have the usual additional options that go along with the sauces (minced daikon, chopped green onions, minced garlic, hot drops, etc...some restaurants have sauce stations with even more options).
I have only been there once and have not tried any of the other dishes. They seem to have a very cool menu with very unique fusion foods so I may venture there again but definitely not for shabu shabu.
