What is the most romantic date you have been on?

What made it the most romantic date you have been on? It could be date night 20 years into a marriage or a first date, etc. If you have not had a date that sticks out as extra romantic, what would your dream date be that is realistic. Realistic - rented a hot air balloon. Not realistic, we flew to Paris.
