Restaurant Daily Specials Post Generator (n8n + OpenAI)

Generate restaurant daily specials posts with OpenAI—directly from an n8n form

Streamline your daily specials workflow: staff submit today’s special in an n8n Form, OpenAI drafts a ready-to-post Instagram, Facebook, or Google Business Profile update, and an on-page review lets you edit before copying the final text.

What this workflow does

• Collects daily special details via an authenticated n8n Form Trigger (dish name, description, optional price, platform choice, and extra notes).
• Applies your restaurant settings (restaurant name, area, brand voice, and emoji/hashtag preferences) to build a platform-specific prompt.
• Generates a draft with OpenAI tailored for Instagram, Facebook, or Google Business Profile.
• Runs rule-based validation and cleanup to produce a compliant, consistent draft—e.g., keeping the price exact, limiting emojis, removing unsuitable hashtags, and stripping phone numbers/links for Google posts.
• Shows a review page with the draft and check notes so you can edit, approve, or discard.
• Returns “Ready to copy” text with brief instructions for posting on the selected platform.

Use cases

• Fast same-day specials: staff submit updates in minutes—no manual copywriting.
• Multi-platform consistency: one entry generates drafts for Instagram, Facebook, or Google Business Profile.
• Brand voice + compliance: enforce your emoji/hashtag rules and keep Google posts free of phone/links.

Technical details

• n8n Form Trigger for authenticated submission

Setup tip: update workflow Settings (restaurant name, area, brand voice, emoji allowance, default hashtags, and max hashtags), publish, then use the generated production for daily specials.
