## Key Learning Points

* Multi-branch decision flow design
* Reservation node and information collection
* Seat availability check and fallback options
* Handling user acceptance/rejection of alternatives
* Node connections and flow completeness

## Steps

1. **Add a Reservation Node**
   * Add a "Reservation" node to the conversation flow to collect user info: number of people, time, special requests, etc.

2. **Branch Handling**
   * Check seat availability:
     * If available: go to "Register Reservation Info" node and complete the booking.
     * If not available: go to "Offer Alternative" node.

3. **Alternative Branches**
   * If user accepts the alternative: go to "Register Reservation Info" node.
   * If user rejects the alternative: go to "End" node and thank the user.

4. **Node Connections & Save**
   * Ensure all nodes are connected so the flow can be saved successfully.

5. **Test the Flow**
   * Test the reservation process, verify info collection, branching, and final booking result.
