We inherited the sideboard and recently bought a new dining room table. I am looking for opinions on whether we should replace the sideboard, if so any suggestions on what would look great? Or whether you would keep the sideboard as is or refinish it?

We are getting rid of the dated liquor cabinet and mirror.
We will be getting an area rug to go under the dining room table and we will be replacing the chandelier. So any suggestions for those as well as decor for tables and wall would be appreciated!

I have also posted a picture of the living room which is attached to the dining room.

Thank you!
