There are a few ways to make a bar cart look prettier. First and foremost, keep the items sitting on it clean and dust-free. Then add accessories that serve a functional purpose and still look stylish. For example, swap out classic clear wine glasses for gold-rimmed sets or replace plain plastic trays for patterned or stone versions. Lastly, add a focal point. Something like a small plant, a candle, or crystals can make your bar cart pop.
