Make sure to have enough ice.
The last thing you'll want to do is run to the store for more ice while your guests' drinks run dry. Make sure to get enough ice ahead of time for the number of guests you're inviting. Also fill your ice trays earlier in the day for backup.
Stock a variety of mixers and garnishes.
You may be set on serving a signature cocktail for the evening, but just in case it's not everybody's style, keep a variety of drink mixers on hand. We recommend tonic water, cranberry and orange juice, a variety of sodas, and margarita mix. Set out basic garnishes like lemon peels, lime wedges, and maraschino cherries, but don't be afraid to get creative as well: fresh herbs and berries would be fun and pretty. You may want to have a few bottles of wine and a six-pack of beer in the refrigerator just in case your guests don't drink hard liquor.
Don't forget about music.
Sometimes it can take a while for lively conversation to develop, and nothing is more awkward than a silent room. This is where background music comes in very handy. Spend a little bit of time developing a playlist for the evening that matches the mood you're trying to set. Choose calmer songs for the beginning of the evening, and as people start to warm, the music can, too!
