NA groups vary wildly from one another. Everything from super posh and very solution focused, to serious I've been in nicer crack-houses with people using in the hallways and throwing furniture in the room between bouts of horror stories. In general the nicer the area, the longer the recovery time, and more solution based the meetings are.
There really are all kinds of meetings, though. From hiking at dawn up a mountainside, to a cozy room with a fireplace above an artsy cafe, to a greenhouse meeting in the country, to church basements damn near everywhere. Similarly, some focus on certain drugs (there are opiate meetings, Rx meetings, stimulant meetings, etc.). If you're going to try NA? I would commit to going to at least 7 meetings (each on a different day of the week, each in a different location) to get a feel for all the different local "flavors".
I very strongly recommend babysitting. People are not only clearly talking about drugs, but there are often people in crisis; suicide, rape, child abuse, etc. If there aren't a lot of NA meetings nearby, or none provide childcare? AA is a much larger organization.

I am neither for nor against 12-Step programs. They're helpful for a lot of people. Not helpful for others. I spent a few years in the program, but I'm not an addict, even though I've picked up a few physical addictions here & there. Kicking sucks. But for me there was nothing beyond the basic kick. I was abusing anything available to cover up or manage PTSD symptoms. Went to treatment, and the center caught on to that pretty quick... So to spite them (and not have to face trauma stuff) I stayed clean for a few years. Eminently distracting, not having to face what the real problem was, and I did learn some things. Quite a lot, in point of fact. But substance abuse was a symptom of my problems, not my problem itself.
