Question

select three things to consider when choosing a restaurant.
whether the restaurant has healthy food options
whether the restaurant is up to code
whether the restaurant is fully staffed
whether the restaurant has a health certificate
whether the restaurant provides free refills

Explanation:

When choosing a restaurant, healthy food options are important for dietary needs. A health certificate indicates compliance with health standards. Whether the restaurant is up to code (safety and regulatory compliance) is also crucial. Staffing levels might vary day - to - day and free refills are more of a minor perk compared to the others.
