I'm running out of date night ideas. Can anyone recommend?

You can try going on an Escape Room experience. There, you and your partner will be thrown into an imaginary scenario and have an hour or so to solve puzzles and crack codes in order to "win" and escape. It's a popular activity in Singapore of late because it promotes teamwork, intelligence and it's really fun. I've been to a few and I must say that I've enjoyed myself thoroughly. Here are some places that offer this Escape Room experience in Singapore: http://weekender.com.sg/w/the-5-best-escape-games-singapore/
