As the title. It used to be in teriyaki restaurant kitchen. The same used at Asian, Mexican est. restaurants. It has a wide platform to hold container etc easy to severing. Most steamers have no such design. Also with two levels stainless steel shaft on top though the holding bar is not which can be painted. So it is not only a steamer. Using gas steamer can save you operation cost. The list price is lower than electronic produce 1.2k (higher energy bill).
