Always be very nice to the caterers/waitresses and it’ll pay dividends in the form of good food.
Best buffet? We played at a Christmas party put on by a mega hotelier. He had top waiters from most of his hotels just serving the buffet. We went up and the guitarist exclaimed ‘have you seen the raffle, guys?’ Fool, that was the buffet.
Going home, I slid the car off the road. It was that good.
