I've never gone to Libido Lounge since it's inception...but I have had the privilege of attending a few or Jennifer's workshops in the year or two before she opened the lounge.
There's a variety of workshops they offer on several subjects...the ones I've attended are certainly well suited to people new to the subject, or just curious about learning more. In fact it was her workshop on Polyamory a couple years back that swayed my wife to try this path again (since the poly role models we might have seen in earlier years were not the sort of people we wanted to emulate).
So...in terms of being worth the couple hours to get to...I would say absolutely yes. It's not miracle work or anything...but Jennifer is an awesome woman, and the workshops are very informative...so if it's education you're looking for, I think it'd be a worthwhile place to seek it.
