I literally stopped because of the long line of hungry people picking up boxes and shoving money at the cashier. The concept is simple. You pick up boxes of prepared sushi, gyoza, and seaweed salad from the open cabinet. There are cold drinks in the fridge or you can scoop up some miso soup as you wait in line. You pay (~$5 for a maki, ~8 for sushi) the cashier by the door and walk out with a good lunch in hand.
The maki itself is heavy on the rice but there is enough of fish and avocado to make it delicious. The rice is soft and well seasoned, so it makes for a filling meal. Good option for a simple weekday lunch on the run!
