How sushi is ordered
Sushi is bought as sets for two or four people, frequently with substitutions, and almost always for delivery. Every substitution taken by phone is a possible error on an expensive order. Delivery timing matters more here than in any other cuisine, because the product degrades and a late arrival is a complaint rather than an inconvenience. Allergen and ingredient questions are constant and answered inconsistently by whoever picks up.
What we build for a sushi bar
First, a set builder with substitutions priced live, eliminating transcription errors on high-value orders. Second, ingredient and allergen information per item, which removes a whole category of phone questions and a real liability. Third, delivery with realistic timing and zone limits, since promising speed you cannot hold destroys the product. Fourth, reorder from history and loyalty, because sushi customers are repetitive and worth keeping off aggregator platforms.
