Oh, yeah, it's great for that niche. But it's hard to break out of that niche.

It's also hard to grow that niche. If 20% of people in the bar are ordering NA beer, it would seem to reduce the pressure to be drinking beer at all, or perhaps going to the bar at all.

If we time traveled to the future and you saw 90% of patrons drinking NA beer at the bar, you'd think it was a historical reenactment.
