This is my favourite, favourite, favourite Japanese restaurant in the world.
Hit this place up around lunchtime. When it comes to the lunch specials, you can't go wrong. I always come for lunch, and I order the exact same thing every time: the Sushi Lunch. There's a selection of different rolls from which you can choose two. You get six of each along with miso soup, salad, and tea, all for $5.99. Cheap AND delicious, not to mention perfect if you're short on cash.
