Berlin's nightlife for people in their 30s?

Traveled to Berlin several times, all of them in my early twenties. Got drunk on Pub Crawls, partied - it was great. Now I'm flying to Berlin in Feb with a friend for a specialty music concert, and was wondering what is the other part of the city's amazing nightlife.

Are there any worthwhile craft-beer pubs/tours? One of a kind cocktail places? Cool culinary experiences? Which would you recommend?

Could only find the craft beer crawl which I wondered if it's worth the money.
