Sushi cases are short, long refrigerated cases that are placed on then countertops of sushi bars and are used to display uncut fillets of various fish. When searching for a case, be sure to check the overall width and compressor location to make sure the unit will suit your needs. The compressor on sushi cases is either on the left or right side. Some models even require a remote compressor to be purchased separately. Remote compressor models maximize the available storage and display space. If you decide to go with a self-contained unit, make sure the compressor is on whichever end of the counter that customers will not be sitting at. One of the appeals of a sushi bar is being able to see the fresh fish up close and watch the chef select and prepare the rolls. And the experience can be ruined if a patron has to lean over to see past the compressor.
Another consideration is the overall width of the unit. Measure the width of your countertop before making a final decisions, so you can be assured that the case will actually fit on your counter.
