In my small town in South Carolina, we're just about to get our third new independent brewery in 3 years. The oldest of the three is already talking about moving to larger premises, and both those currently in business are canning their beer with sales already in hundreds of retailers across the region, in addition to selling beer on site.
All of them brew at least one light American pilsner to appeal to newcomers and also offer a decent food menu and regular special events. I don't think these kinds of places are going away any time soon. They offer an ambience and clientele that's distinct from a regular restaurant or bar, and I've found myself visiting them more frequently as they continually experiment and improve their beers.
