To the poster above me, pork fried rice isn't Japanese food. It's Americanized Chinese food.
Chinese food tends to be heavier - more spices, more grease - and Japanese food tends to be lighter and more mild. Japanese food is my favorite so I am biased and want to tell you to order anything, because it will be good.
If you want soup, try tempura nabeyaki (nah-bay-yak-ee). It has a few pieces of tempura (lightly fried shrimp), chicken, udon (fat noodles), and vegetables (cabage, bean sprouts). You could always try sushi, too. If you're daring, go for the raw fish - tuna, salmon, and yellow tail are particularly common. Or just stick with the California roll - cooked crab (usually fake), avocado, and cucumber. Please, please, PLEASE do not order chicken teriyaki. You can't even find that Americanized crap in Asia.
