The simplest way to judge the worth of a sushi train is by the number of people perched at the bar. Ichiro’s,which is all bare tables and red lanterns,ticks that box,proving popular with Mascot’s local jet set. At $12.50,the lunch special is a cost-effective selection of three sushi rolls and a hot green tea. The inside-out rolls are a two-bite delight,arriving alongside iridescent seaweed and slabs of pink tuna. The teriyaki chicken don is also lacquered with soy and pelted with sesame seeds and served on a thatch of grated carrot,leaves and a mound of rice. Forgo dessert for a salty,nourishing bowl of miso soup.
