Can you post a photo of the style that you want?

Something like this:

World Market has similar chairs. They are sold in sets of 2 for $460.

They also have a table that would give you a similar look but you might be able to find something closer to the table in your inspiration photo. This table is $550.

Right now their furniture is 40% off plus free shipping. So the table and 6 chairs would be $1233 (includes oversized shipping fee but not tax).

You could also try and diy by adding a piece of wood to the top of your current table, staining the wood, and painting the table base.

I would then sell what you dont use on craigslist and use the money to buy 2 huge mirrors like in your attached photo.

If you bought that dining table and chairs you would need to get a new buffet to go with it.

Your dining room set reminds me of the large hutch from my maternal grandparents’ house. And the table and chairs look like the set from my paternal grandparents.
My sister has the hutch and had it professionally redone - changed from 1960’s fruitwood to pure black. It’s fabulous.
I have the dining room set and just use the Chippendale style chairs (not original antiques). I had them repainted and bought a round small table to go with it. The table folds up and is my serving buffet.

I don’t have a photo of the hutch, but the chairs are below.
If you like your set, you might consider redoing both pieces. Getting ideas on restraining or painting both will give you some ideas.
The hutch is being used in my sister’s living room as a major storage piece.
