FAQ

Why more food on buffet? +
Self-serve = bigger initial portions. Plus people go back for seconds and want choices. Plan for 5 oz protein per person on buffet vs 4 oz plated.
How long should buffet stay open? +
90 min max for food safety. Hot foods at 140°F+, cold foods under 40°F. Replenish in small batches.
Should everything refill at once? +
No — refill in halves so it always looks full but not wasteful. Last 30 min: stop refilling, let it run down.
