The gourmet has not arrived and the food is not ready.

1. The gourmet has not arrived: If the gourmet has not arrived at the destination, he cannot taste and evaluate the dishes in person.

So unable to provide any feedback or suggestions.

2. The dish is not ready: The dish is not ready or ready to be tasted, and the foodie cannot provide any evaluation.

This is because the dish takes a certain amount of time to prepare, or the dish cannot be prepared in time for other reasons.
