Build an AI menu generator web app. 1) Restaurant profile with name, logo, tone of voice and location. 2) Dish library with name, section, price, ingredient list, allergen flags, dietary flags, photo, prep notes and availability, with search and bulk import from a spreadsheet. 3) Menu builder with sections, drag ordering and inline editing, plus preview at print size. 4) An AI description generator that writes from the ingredient list in the chosen tone, supports bulk regeneration with a before and after diff, and never adds sourcing or health claims. 5) A dietary and allergen proposal step that suggests tags from ingredients and requires explicit owner confirmation before any tag appears on the menu. 6) An ingredient cost table with supplier prices, cost per dish, target margin and a suggested price, updating a warning when a dish falls below target. 7) Print export using a layout engine with page size, bleed, crop marks and safe margins, producing a printer ready PDF. 8) A public web menu at its own URL with QR code generation, plus copy blocks formatted per dish for delivery platforms. 9) Version history per menu version. 10) Multi location support with shared dishes and per location price overrides.
