have you tried the table length wise? the beer keg and the cabinet ..... I would do really simple black chairs try looking on pottery barn, id also get a light colored rug to help the base of the table stand out. https://www.potterybarn.com/products/keva-leather-dining-side-chair-mp/?catalogId=84&sku=73649&cm_ven=PLA&cm_cat=Google&cm_pla=Furniture%20%3E%20Dining%20Chairs&cm_ite=73649_14552546110&gclid=CjwKCAjw4JWZBhApEiwAtJUN0AtORpMQZBfvGBAKuqim8XcoOtGrkE7uWl08n7VHkdQdf8XPPKueFBoCyfgQAvD_BwE

Can you show more of the living area? I feel black chairs with a bit of metallic touch might also go well with this set up. You can check something like this -- https://www.casaone.com/us/products/epifania-dining-chair-in-black-with-chrome-legs-set-of-4(cilck here)
