In Duluth, umm, not that I know of.
There is
5 Seasons in Alpharetta which is very near Duluth.
If you want to head back into the Atlanta area there are a few:
-Rock Botton
-Gordon Biersch
-
Max Lagers
Now, even better IMO, in Decatur:
-
Twains
-
The Brickstore, not a brewpub but one of the best beer bars in the area, within walking distance of Twains
If you are looking for a decent (marginally) dinner, bad service, but a good selection of draft beer, you should check out
TacoMac. I know there is one in Duluth.
