You've had your fake-crab California roll a million times. Sure, you like it. And yeah, it's comforting — the blankie of sushi. Well, kids, it's time to grow up in the world of Japanese cuisine. There are things going on outside that Americanized roll universe that you couldn't even dream. Like Imoto's special nigiri. Sticky yet downy mounds of rice are topped with the most decadent combination of ingredients. Fluke nigiri ($4.50) comes topped with foie gras, momiji, scallion, and ponzu. Scallop nigiri ($4) boasts lemon, shiso salt, and tomburi. Lobster nigiri ($7) is delicately layered with ginger sauce and fried shiso. What? You need something more? Imoto is open.
