I love the idea of having a bar station out during a party so guests can help themselves. It's sets a retro laid-back vibe for a party. No need to put out anything too fancy, just enough for a couple of classic cocktails that guests can make just to their liking. We had one out at our last party, and it just had the staples on it - gin, vodka, bourbon, tequila, orange and tomato juice, cola, ginger ale, tonic water, lemons and limes. And ice. Lots and lots of ice. A whole party on a cart. Domino has a great slide show up right now with some nicely styled carts to get those ideas flowing.
