Candles, dinner, beloved person, What else you can add? My answer is cocktails yes wine is good but some people don't like it (beer, vodka, etc - the same situation). You can prepare different cocktails with the person you love (And have fun during preparation) and then have a nice romantic dinner together or you can just take some cocktails and spend evening with each other. Cocktails could help you to relax and just cheer up. You can also take decorative cups or glasses or something and your cocktails will be very beautiful (and tasty).

Do it and you will have nice romantic evening with your beloved person.

(My advice- Use chilled champagne to prepare cocktails)
