Restaurant Voice Assistant: VAPI + PostgreSQL Bookings & Orders

This n8n workflow creates a comprehensive voice-powered restaurant assistant that handles table reservations, food orders, and information requests via natural language. Powered by VAPI for real-time voice interactions and PostgreSQL for secure data storage, it processes customer calls to extract details like party size, booking times, and menu items, then confirms via voice while logging everything in dedicated tables (bookings, orders, restaurant_info).

Key features include real-time database operations with immediate confirmations, support for multiple simultaneous calls, and conversational responses for queries on hours, menu, or location. Wait nodes ensure smooth data flow, and all data is indexed for performance. Benefits include automating customer service, reducing staff workload, and providing 24/7 availability, ideal for busy restaurants seeking efficient voice AI solutions.

Use cases: Small to medium restaurants for reservation management; quick-service spots for order intake; any eatery wanting voice-enabled self-service. Requires VAPI subscription (per-minute billing) and PostgreSQL setup. Easy to customize with your restaurant data for scalable automation.
