Your room is big and void of color. Yes there is too much brown. If not replacing. Add light colored pillows big in a cream print. Add teal to mix. Get a 8 x10 area rug. Go cream base and a contemporary design in very bold colors, red, yellow and black, teals mix it up. Can you get regular chairs. Those look like game chairs, can they go in kids room? Pull sectional into room out of corner face TV wall. With big rug and a 36" ottoman square. In a color. Maybe zebra for fun. On TV wall. Get a wall to wall floor to ceiling or close to it wall unit. Ikea has some go white. Get. Long low media cabinet. Also Ikea in white. Place TV on top. Fill wall unit with colorful pots candles books. Just don't over do leave 50% empty. You could paint that wall a darker (2) shade of walls. After you have centered sofa in room more. On wall behind a very large art contemporary 40x40 hang very low. On empty wall in dining area. Get a long 6-7 ft chest. Something different. Asian feel red lacquered would be fun. Over it add big art piece bold colors 40 x40 hang 6" above top of cabinet. More art big by dining table. I would change chairs to a high back leather in Teal. Pier one has them. Your whole place needs color. Area rug under table 8 x10. Solid teal. Add big palms in corner to fill and warm up space. In chairs get two swivel barrel type in a print. Modern go taupe and blue/greens. Wi Dow panels on ends only in teal. Ck bed n bath. TJMax a good source. For art ect.

Yes, JudyG that's exactly the way people were using the taller table. Sort of a café look, or casual bar setting. One home had a beautiful huge kitchen all done in white with dark wood floors and RH style fixtures and hardware. Where you would normally think would be a traditional dining room, they had made it up with a large high table and 6 barstools. It almost looked like an extension of the island. Another one was in a very open and light kitchen. It was smaller and where you might think of putting a breakfast nook they had a round café-style table with four barstools. I liked it because it gave a more casual appearance. If people were sitting at them, they were on the same level as those working in the kitchen. Almost like a bar at the island for that effect, but with some separation.

Better to open both the doors... make a sliding door. Better than a mirror look for clean half white colour paint or laminate for wine storage above. Put more of ceiling lights to see highlight the niche for easy working. dim light are only used where a person is seating to have his drink and not at the place where he store the bottles...

The red brick wall as a backdrop sounds very interesting. You can get quirky posters of various liquor brands like Jack Daniels, Chivas etc in black and white and get it framed and put them on the wall. Also industrial look is very in so the bar top can be done using a copper sheet over a plywood top instead of traditional granite or marble. Also utilise any empty beer bottles or wine bottles to make a customised chandelier. For stools you could have wrought iron stools with leather seats matching the brick wall. A small wall shelf with a display of shot glasses will make the look more interesting. Hope this is helpful, it will be great if you can share pictures of the area to give some more inputs.
