Hanabi went from a paper notebook to a fully digital restaurant

We started with the brand: a cleaned-up logo, color palette, typefaces, food photography and a 34-page brand guidelines book so menus, bags and social posts all looked consistent. On that foundation we built a static website with the full menu, a photo of every dish, filters (spicy, vegetarian, gluten-free) and a QR code on every table that opens the menu right on the guest's phone.

Delivery orders are built inside the same menu: the customer adds dishes and the "Order on WhatsApp" button opens a chat with the order, address and payment method already filled in. After the meal, a second QR code printed on the receipt leads to a five-question survey that feeds a weekly dashboard for the owner.

For operations we built custom software: a point-of-sale system in PHP 8 and MySQL with kitchen tickets, split checks and automatic register closeout, plus an Electron time-clock app that talks to the fingerprint reader through a C# bridge. Every clock-in and clock-out lands in the same database payroll uses.

Six months after launch, Hanabi averages 406 WhatsApp orders a month, up from 143 before the project. Because every message arrives complete, nobody has to ask for the address or repeat the order, and kitchen mistakes from badly written tickets have all but disappeared.

Register closeout went from 48 to 17 minutes, and payroll is built from the time-clock report with no sheets and no arguments. The survey has collected 612 responses with an average rating of 4.6; it showed that weekend wait times were the top complaint, so they opened a second sushi-bar line on Saturdays.
