Sushiro Iconsiam is a conveyor-belt sushi restaurant on the UG floor of Iconsiam in Bangkok, serving Japanese-style sushi. Sushi can be taken directly from the conveyor or ordered on a tablet, and the menu has a wide range of choices. Before noon, you can sit down without waiting. The standard conveyor sushi comes with a large portion of rice, so you need to choose the option with less rice.
