Great sushi has never been cheap, but no one else in OC has been able to get away with charging as much as James Hamamori does. Dinner for two at his eponymous South Coast Plaza eatery will climb into the triple digits faster than you can say "omakase" ($80 per person for food, an additional $40 for wine or sake pairing). This is the reason why you should get someone else to pay for it. For example, a repentant boyfriend trying to make amends, or that sales exec who's desperate to get a signature on a dotted line. Let them buy your way into your good graces with a meal prepared by Hamamori himself; a sushi feast to break bank accounts and breach credit limits . . . just not your own.
