Question

Are those killer sushi "boats" in restaurants culturally based and how can I find some at a reasonable price?

Answer 1

Answer 2

In Japan, and increasingly abroad, conveyor belt sushi/sushi train (kaiten zushi) restaurants are a popular, cost effective way of eating sushi. At these restaurants, the sushi is served on color-coded plates, with each color denoting the cost of the sushi serving. The plates are placed on a conveyor belt or boats floating in a moat. As the belt or boat passes, the customers choose their desired plates. After finishing, the bill is tallied by counting how many plates of each color have been taken. Some kaiten sushi restaurants in Japan operate on a fixed price system, with each plate, consisting usually of two pieces of sushi, generally costing between ¥100 and ¥200.

More traditionally, sushi is served on minimalist Japanese-style, geometric, wood or lacquer plates which are mono- or duo-tone in color, in keeping with the aesthetic qualities of this cuisine. Many small sushi restaurants actually use no plates — the sushi is eaten directly off of the wooden counter, usually with one's hands.

The cheapest sushi boats i found were online at amazon.com

you may be able to find them if your city has a china/asian market.  usually they will have a restuarant supply store that sells them.
