Directly across the street from the (in)famous RAKU. Where Raku tries to portray a hip urban Tokyo vibe, Swish is like walking into a neighborhood eatery somewhere in working class Japan. Me think that a good thing.
I have been to several Shabu Shabu locations in SoCal and even though Swish is a no frills version, I like it the best. Service is very attentive-and helpful- without being suffocating as many Asian places can be (got to turn those tables...).
Food is very good and has generous portions. Prime Rib is really the best option. Beer is a nice compliment on a warm spring day but remember that Japanese beer is like a light-light version of its American counterpart.
Take a nice three hour hike in Red Rock and stop by Swish on the way home. You won't be sorry.
