Koku Sushi is a Polish chain of sushi bars that grew from a single family-run restaurant into a nationwide network and became the country's largest domestic sushi chain. As an operator, its key edge is a tiered range of formats: a compact delivery-only POINT with no dining area, an entry sit-down BASIC bar, a standard restaurant, and a high-end PREMIUM venue suited even for events. Instead of one rigid template, you pick the format to match your city, budget and available premises.
