Sushi display case guide: refrigerated countertop cases for sushi bars

What a sushi display case is

A sushi case is a low, long refrigerated display that sits on a counter. Inside, a chilled deck holds trays of prepared fish and toppings. A curved or angled glass canopy faces the customer, and the chef reaches in from the back, often without doors or through sliding panels. The format is compact and shallow so it does not block the chef's view or the customer's.

Temperature for raw seafood

Raw fish for sushi and sashimi is highly perishable. Common food-safety guidance is to keep chilled perishables at 5 °C or below, so run the case at the colder end of its range and probe-check the fish itself during service. A refrigerated display holds roughly +2 to +10 °C depending on design; it keeps prepared fish cold through service but is not a storage refrigerator. Keep the bulk of the fish in storage, colder, and bring out what the next part of service needs.

Drying and colour

Cut fish loses moisture and colour when cold air moves across it. Tuna in particular darkens as its red pigment oxidises, and the change continues even at chilled temperatures. Gentle cooling helps: many sushi cases use a chilled deck or static coil rather than strong fan-driven air. Where a fan is used, check that air does not blow directly over the trays. Cover cut blocks, display small portions and replenish often, so what the customer sees is always fresh.

Cooling options compared

Construction details

• Stainless steel deck and trays that resist salt and fish juices; ask which grade.
• Curved front glass that is easy to clean, ideally lifting or removable.
• Low-heat LED lighting that shows colour accurately without warming the fish.
• A drain or condensate tray that is easy to empty and clean.
• A slim profile, so the chef can pass plates over it comfortably.

Fitting it to the counter

Measure the counter depth and the chef's working space behind it. The case should leave room for a cutting board and plating in front of the chef. Sushi cases come in modular lengths; choose a length that holds every topping the menu uses at once, with room for specials. Check where the refrigeration unit sits — built into the case or below the counter — and plan ventilation for it, because a unit boxed into a closed counter overheats. Check the height too: the case should let seated customers see the fish clearly without forcing the chef to reach over a tall canopy. Finally, plan a socket and a route for any drain line before the counter is built, since retrofitting them into finished joinery is expensive and messy.

Hygiene routine

• Keep raw fish in covered trays and use separate boards and knives for raw seafood and other items.
• Return all fish to storage refrigeration at the end of service.
• Wash trays and the deck daily and sanitise according to your food-safety plan.
• Clean the glass inside and out; fish oils and fingerprints build up quickly.
• Log temperatures at opening, during service and at closing.

Not only for sushi

The same compact refrigerated case works well for other counter displays: cut fruit at a juice bar, garnishes and cold starters at a hotel live counter, small desserts in a café, or salads and cold mezze. Anywhere food is prepared to order in front of customers and needs to stay cold and visible, a sushi-style case can be the right tool.

Questions to ask the supplier

• What temperature does the deck hold, and at what room temperature?
• Is cooling static or fan-assisted, and how does the air move over the trays?
• What lengths are available, and how many trays fit?
• Where does the refrigeration unit sit, and what ventilation does it need?
• Does the glass lift or remove for cleaning?
