Caveat
Run 1 hits a cold CDN cache, so it is the slowest. On a simulated slow phone the same sites score between 67 and 77.
Stated
Numbers without runs come from the project record, not from a measuring tool.

Coffee World shown on a phone

01Problem

Café menus were PDFs. Guests scanned the QR code at night and found nothing they could read.

"I just wanted to know what the drinks were, but the PDF was too dark to read on my phone."

Field observation, Ladadika, Thessaloniki
  1. Goal 01Greek and English that never break the layout.
  2. Goal 02A dark, premium look that suits an evening café.

02What was built

  1. 01

    QR first

    Nothing to install: the QR code opens a category in under 2 seconds.

  2. 02

    Bilingual by default

    Every item and description exists in Greek and English, so neither reads as the translation.

  3. 03

    Boutique dark

    Deep forest tones and gold accents that match the room the menu is read in.

03Process

  1. 01

    Field research

    Time in the Ladadika café scene. PDF menus were the main friction for international guests scanning at night.

  2. 02

    Information architecture

    One flow: QR scan, category, item - under 2 seconds. The structure mirrors the physical menu.

  3. 03

    Visual language

    Deep greens, gold accents, Playfair Display for headlines and GFS Neohellenic for Greek body text.

  4. 04

    Testing and refinement

    A field test with one participant (Ioanna, 46): the look earned trust at once; the horizontal scroll cue needed a second pass.

05Lesson

In a luxury café, a menu you can read at night on a phone is part of the luxury.
