When we talk about service design, we often think about big systems or major journeys. But some of the most meaningful improvements happen in the small details. A recent restaurant visit reminded me of this. I noticed a simple change in how allergy information was shared with customers, and it showed how thoughtful design can quietly make a big difference.
If you have eaten out in the last few years, you will have seen how seriously restaurants now take food allergies. In many places, when someone in your group mentions they have an allergy or intolerance, the waiter or waitress pulls out a hefty folder or book packed with information about every dish on the menu.
Recently, during a meal out, I noticed something different. Instead of the usual printed book, the restaurant handed us an iPad. It held a digital version of the allergy information.
This small change made a big difference. It was much quicker and easier for both staff and customers to find the information they needed. Instead of wading through hundreds of printed pages, we could search by dish or ingredient and get the answers right away. It also meant the conversation between customer and staff felt more natural and less awkward. No one had to spend five minutes flipping through a massive book while the rest of the table waited.
From the restaurant’s side, the digital allergy book offers real advantages. They can update the information immediately if a recipe changes or a new dish is added. There is no need to reprint dozens of pages or worry about whether every copy is up to date. It saves time, reduces printing costs, and lowers the risk of mistakes.
From a UX and service design point of view, this is a great example of how a small, thoughtful change can improve the experience for everyone. It meets a real need, removes friction, and helps businesses stay compliant with regulations. It is a reminder that designing good services is not always about big overhauls. Sometimes, it is about finding simple ways to make real improvements.
