The dining set and chandelier are traditional. Will you be replacing these things or are you just looking for a way to blend in items to reflect your modern taste with what is already there?

What isThat dark cabinet door whatever it is by the gate? Let's remove that table that's in the corner from the room that's an end table or a nightstand for one of those rooms if you have a cabinet like an armoire or side bar table Buffet style it can go on the left wall if it's long as you enter from the gate or if it's more narrow it could go by the doorway by the window

Do you already own art that you’d like to display in this room? If not, I’d start looking for a nice big piece for the wall opposite the window. I’d also look for a modern chandelier in a size that better suits the size of your dining table. I’d keep the room as clutter free as possible since the room appears to be fairly narrow.

That beautiful lamp sitting on the table would look great on this modern cabinet placed to the right of the doorway.

I don't know how far you intend to go so I kept the walls the gray colour they are with white trim as well as your table and chairs. You say your style is contemporary modern but your chandelier, table & chairs, and room style in itself is not contemporary modern.

So... I show a new pendant and sideboards (3 together - Crate-& Barrel) with some decor including white side drapes on a black rod.

The room looks dark but probably because you had the shutters closed when taking the photo.

I’m open to removing anything but the dining table since we just got it from a friend. I’ve got a little makeshift bar in the corner. Could I use a table or buffet table for alcohol instead? I’m scared to add a table since the room is narrow but I’m open to anything.
