The only brew I like by Moonriver is their Swamp Fox IPA. I don't recommend anything else there (well, he made something else once I liked, but I don't recall the style, it was called subzero or somesuch) I found his dry stout to be too whispy at 3.2% abv, and his belgian styles range from farty to fusel. I guess the Abberation Ale is ok too.
I've found the service to be meh at best but the food is pretty good. Overall, I'd say if you are hungering to hit up a brewpub its a decent place to go. But I've pretty much worn out my interest with the place.
Habersham Bottle shop in Savannah has some nice brews in stock.
