AI-Powered Restaurant Booking via Telegram, Calendar & Email

This workflow powers an intelligent booking assistant for restaurants and events, triggered via Telegram bot. It engages users in a natural, step-by-step conversation powered by AI (OpenAI or OpenRouter), gathering essential details like guest count, seating preferences (indoor/outdoor/private), special requests, date, and time. Once collected, it generates a draft summary for user review and confirmation, then prompts for personal info (name, email, phone).

Upon final approval, the system seamlessly creates a Google Calendar event for the reservation and dispatches a professional email confirmation with all details. A closing Telegram message ensures the user knows the booking is complete. This end-to-end automation handles everything without human intervention, supporting 24/7 operations.

Benefits include massive time savings for restaurant staff, reduced booking errors, enhanced customer experience with conversational AI, and scalability for high-volume inquiries. Ideal for restaurants, cafes, event venues, or any service needing reservation management. Setup requires Telegram Bot Token, AI API key, Google Calendar credentials, and email service—deployable on self-hosted or cloud n8n.

Use cases: Automate bookings for busy eateries, integrate with existing calendars for real-time availability (extendable), or adapt for hotels/spas. It transforms manual phone/email bookings into efficient, AI-powered interactions, boosting conversions and satisfaction.
