Whenever I have a dinner party, I like to have a bar set up with great glasses, alcohol, mixers, ice, cocktail napkins, lemons, limes, some type of finger food (like nuts, chips or olives) and maybe a small vase with flowers. I do the same for brunches with coffee, tea, mimosas or bloody marys and some type of cookie or sweet.
I think I was originally inspired by the first photo (from House & Garden a few years ago) and a few others like it that I pulled from magazines. I bought a great butlers table from an antique store that folds up for easy storage and I always bring it out for parties. I'm working on a post with butler's tables and bar carts for ideas of where or what to buy for your next party.
