Background & Challenge

Quantum is a quantum fine-dining restaurant “without a home planet,” perched at the silent edge of everything. The website’s job is not to explain the food, but to build an atmosphere of calm, precision, and surreal luxury—then convert that belief into reservations and purchases.

The challenge is that it serves two kinds of readers: brand visitors come for the atmosphere and need an editorial landing page that unfolds the worldview at its own pace; buyers are already convinced and head to /order for meal kits, wine, and merchandise, expecting a mobile-first, friction-free flow. Two interfaces with very different personalities must still speak the same language—exactly the problem a design system exists to solve. The side-by-side Traditional Chinese and English is a brand statement, not an add-on feature.

Design Decisions

The Chef section: a dithered portrait of the chef on the left, with the Fraunces italic quote 'I came a long way to simmer something very small.' and the name Zx'ira Tanaka (Chef · Founder) on the right
Chef section: a Fraunces italic quote, instrument-readout labels, and a dithered portrait — the north-star visual language in practice
Menu section headlined 'Six dishes, one evening.', each dish with a quantum-violet dithered glyph illustration on its left
The six DishGlyph dithered illustrations, generated from density fields and seeded dithering
The checkout flow: a four-step StepIndicator at the top (delivery, identification, payment, review), a delivery-details form on the left, and an order summary on the right (Event Horizon Kit, Photon Broth Kit, total $920)
Ordering checkout: the four-step flow and the StepIndicator shared with reservations, converged after benchmarking mainstream checkout conventions with Mobbin

Outcome & Reflections

The result is a React + TypeScript + SCSS project: an editorial brand landing page plus a complete ordering journey from store to four-step checkout, with built-in light/dark themes and bilingual side-by-side text, handling contrast and prefers-reduced-motion fallbacks against a WCAG 2.1 AA target.

Looking back, the biggest lesson was “write the worldview first, then set the rules”: with a north star and an explicit anti-list, component-level trade-offs got faster—whenever I wanted to add a shadow, I first asked whether it should be a hairline instead. A fictional restaurant with nothing to photograph forced a second lesson: a homegrown dither engine let the brand grow its own illustrations, so the visuals became part of the design system—like the tokens and components—rather than outsourced decoration.
