The Denver Museum of Nature & Science sounds like a place you might visit on a school field trip, but their Science Lounge events geared toward adults have turned the place into a date destination. Mixing cocktails and entertainment with science, the DMNS Science Lounges are both informative and fun. The next event on February 19 is all about space ships, and attendees will learn the basics of rocket science, including how vehicles are launched into space, before sipping cosmic cocktails. Have a beer about a mile away at Vine Street, a casual, low-key spot that's known as Denver's best brewpub after the experience.
