When describing your setting, consider who's looking at it as well as what they see. For example, an ex-con is likely to view (and describe) a restaurant hosting a police officer's retirement party differently than the daughter of the retiring officer. Take the point-of-view-character's world view and personal judgment into consideration. What details would they specifically notice? How would they feel about what they see? What emotions or thoughts might those details trigger? This allows you to craft richer settings that reflect both the character, and the world they live in.
