What does it mean to use sensory details to convey a sense of the setting, quality of the food, and the presence of your company during a dinner?

I think that you are being asked to describe the elements
through the use of your senses.  Sensory imagery is a way that a writer is able to
convey the experience of "the moment" by using the senses in order to connect the
instant with the reader.  For example, in conveying the "quality of the food," one can
use the sense of sight in describing how it looks.  Taste would be another sensory image
used to make the reader fully grasp the properties of the food.  In articulating "the
presence of company," how did their voice sound, using the sense of hearing?  What
material comprised the various dresses and suits, which would appeal to the sense of
touch.  In this sensory detail arena, most of what you are being asked to do is to put
yourself in that situation, experience it for yourself, noting everything.  Then, put
the reader in what you were in by conveying to the reader what you experienced.  What
smells were in the room?  In being able to describe the sense of smell, you are able to
connect the experience of being in the room with a sensation that might allow the reader
to better connect with that moment.  Writers always struggle with the recreation of the
moment because words and language limit the reader.  No matter what, there will always
be a barrier between what is being experienced and how a third party will interpret this
experience.  The use of sensory imagery and sensory details helps to bridge this gap
because the writer is able to link what they experience through the use of the senses,
something that can be easily identified by the reader.
