Take a class together. A local college or university usually offers evening classes for continuing/Adult education.
Sign up for something interesting. Our first class togther was "Thursday Night Supper Club" at Emory. Hey, it guaranteed me four more dates! Plus, we made some friends out of the experience.
Our next class was "Christianity and World Religions". Once per week, we made an entire evening out of it. A quick dinner followed by mental stimulation and interesting conversation after the class.
Next, we'll be signing up for "Dance Instruction for the Bride and Groom" as we are getting married next year. She's also scheduled for "How to Plan a Wedding".
Find something that looks interesting and you can learn, experience and grow together. Good dates don't have to be expensive.
Good luck!
