Here's an idea for a small bar in a corner that you could close off with beautiful draperies. The second photo shows a pretty bar cart which could hold the necessary items, and the third photo is of a simpler butler's tray.

Your white walls are too stark for your wood trim. Softer whites and other tints might warm up the room. Lots of Houzz discussion lately on best paint colors for rooms with wood trim. Here's a classic Houzz article about some great colors that work with wood trim like yours: https://www.houzz.com/magazine/11-terrific-paint-color-matches-for-wood-details-stsetivw-vs~9025200 Here's a Google link that comes up with the search: "paint colors for wood trim" http://www.google.com/images?client=safari&rls=en&q=best+paint+colors+wood+trim&oe=UTF-8&hl=en&sa=X&oi=image_result_group&ei=wtHIVPT-OcyYNtWehLAN&ved=0CC0QsAQ Additionally, like the others, add some lighter pillows to your couch--or a couple cozy throws--based on colors in your rug. A large round glass coffee table would showcase your beautiful rug as well. You could add accessories on the coffee table in colors from the rug. Yes, hanging plants in each window.

Your setting is good but could be better.the centre table is a misfit.you can use 2 level rectangular table either white poly paint one level and the other level glass or black paint or poly paint.keep the length of the table after leaving approx 16 to 18"on either side.the width can be20-22 " and ht 16".the cushions can be change to black and white design,with a dash of red.a nice rug with grey,black and white geometric design will enhance the effect.brown does not go well with white.i hope this should solve your problem.once you make this change.you eye will pick up the other flaws.

very good looking with this budget I would like to go for it.
