A QR code does not fix connectivity. The guest's first experience depends on how fast essential menu text appears.
Prioritise words before glossy media
Dish names, prices, category navigation and availability should remain legible even when a large food photo has not loaded. Compress images, use correct display sizes, lazy-load below-the-fold media and avoid excessive third-party scripts.
Minimise the route between scan and menu
Do not require an unnecessary download or profile screen to read available dishes. A table QR can open directly in the browser. Make back navigation predictable and do not hijack the guest's device or lock scrolling.
Test outside the restaurant Wi-Fi
Compare a fast desktop connection with an average Android handset on mobile data. Check for service-worker or caching mistakes that might show old prices. Staff should have a printed or spoken alternative whenever the network fails.
Here's what this looks like in practice.
Illustrative situation, not a claim about a real KyaLoge customer.
A phone on slow mobile data opens a menu with a full-screen image and several external scripts. The guest sees a spinner and gives up even though the dish list itself is only a few lines of text.
A better way to handle it
Prioritize headings, prices and categories in initial HTML, reserve space for media and load images progressively. Test the experience without an image connection. Retain staff service if the entire system is unavailable.
Disable images and throttle mobile network conditions in DevTools. Verify a guest can still find the menu category and read the price.
Evaluating performance only from a fast laptop on office Wi-Fi.
What to check before making a decision
- 01Simulate a slow 3G-type connection.
- 02Inspect the page with images blocked.
- 03Make sure the page title and price text are server-rendered.
- 04Provide a visible way to ask staff for help.
Keep the useful part.
Speed is part of accessibility and usability. Treat performance measurements as ongoing product work, not an unverified marketing claim.
