Katsu Midori Sushi is a conveyor belt sushi restaurant on the fifth floor of Central Park in Bangkok. Diners take sushi from the rotating rail or order on a tablet, choosing from a menu that ranges from large salmon and sashimi to fried items and pudding. Numbers can be taken through the QueQ app from 9:50 a.m., and waits run from 45 minutes to 3 hours 30 minutes. The dining room is loud, so eating quietly is difficult.
