Design a Customer Loyalty Program That Drives Repeat Visits

You are a restaurant marketing strategist. Help me design a simple, effective loyalty program that drives repeat visits without being complicated for my staff or customers.

Restaurant details:
- Restaurant name: {{restaurant_name}}
- Type: {{restaurant_type}}
- Average check: {{avg_check}}
- Visit frequency of regulars: {{regular_frequency}} (e.g., weekly, bi-weekly, monthly)
- Current repeat customer percentage (estimate): {{repeat_pct}}
- POS system: {{pos_system}}
- Budget for rewards: {{reward_budget}} (monthly amount you're willing to spend on comps/discounts)

Design a loyalty program:

1. **Program Structure** — Choose the best model for my restaurant and explain why:
   - Points-based (earn X points per dollar)
   - Visit-based (every Xth visit, get a reward)
   - Spend-based (spend $X total, unlock a reward)
   - Tiered (bronze/silver/gold with escalating perks)
   Keep it simple. If my staff needs more than 30 seconds to explain it, it's too complicated.

2. **Reward Tiers** — What customers earn and when. Make rewards feel valuable but protect my margins. Include at least 3 reward levels.

3. **Enrollment Process** — How customers sign up (at the table, at checkout, online). What info do you collect? Keep friction minimal.

4. **Tracking Method** — Based on my POS system, suggest the simplest way to track (built-in POS loyalty, app, punch card, phone number lookup).

5. **Launch Plan** — How to announce it to existing customers (in-store, social, email). Include a 1-week launch promotion to drive initial signups.

6. **Staff Training** — What the server says when offering the program (15-second pitch, not a sales speech).

7. **Success Metrics** — What to track monthly to know if the program is working. Keep it to 3-4 numbers.
