Candles. Even a single candle improves the mood. So why not light a few? But remember, save the scented candles for the bath or bedroom. You don't want extra odors to compete with your romantic dinner! 

Music. Don't forget to put on a soft and silky groove in the background. Put that sway into your partner's body. Rock it gently all night long. Wine. Just remember: you're not out to get overly tipsy! 
You're here to toast each other and set the mood. A glass or two of a tasty and drinkable white will go great with Cristina's anniversary dinner. Even better, break out the bubbly. If not on a night like this, then when?
