hef here. I got so tired of the "table 12 wants to know if the sauce has gluten" ticket that I built something. Roast it.
I run the kitchen at a busy spot in Scheveningen (NL). Every service, same thing: a server walks in mid-rush asking what's in a dish, whether we can do it without nuts, whether the fryer is shared. Nobody can memorize 60 dishes × 14 allergens × what's swappable.
So I spent the last months building a thing where the whole menu is mapped once — every dish shows guests: safe / adaptable (with the actual swap, like "we leave out the breadcrumbs") / not possible. Guest scans a QR at the table, picks their allergens, sees instantly what they can order. No more kitchen runs.
We run it live in my own restaurant now. Honest question for people actually on the line: would this help your service, or is it another iPad-on-the-pass gimmick? What would make it actually useful for BOH?
Full disclosure: I built this (allergent.app). And since this community is exactly who it's for — if you run a kitchen and want to try it, use code WELCOME10 at signup for 2 months free. No card tricks, no catch — I want feedback from real kitchens more than I want money right now. Roast away.
